We stayed at the SWBH for 4 nights in Beach House 2 and had a wonderful stay. Do not expect a modern resort with lots of luxury, then you have come to the wrong place. No, this is a "hotel" with a nice last century feel. The beach house was right on the beach with a wonderful view. Local fishermen and their families were bringing in their nets, children and dogs were playing, which made you feel you were really on Flores and not some anonymous resort.
The accomodation is simple but clean. The local staff, with the help of many young students of the "tourism high school" was extremely helpful and always smiling, although their knowledge of English is very limited.
One day we made a tour with the driver of the hotel to an Ikat weaving village, Watuplabi, which was very worthwhile and an other day we went snorkeling with a fishing boat, great fun and all organized by the hotel.
Father Heinrich, a german priest of 81, runs the place and a great part of the money made goes to charity. For example the area is now malaria free! There are two albino monkeys in cages, who are well taken care of, because they would be without a chance let free in nature.
Every day between 4 and 6pm, there is "happy hour" in the bar on the beach, when large Bintang beers are served at a reduced price. Lacking are some small snacks. When we were there a BBQ on the beach was organised, with music and traditional dances performed by young school kids in ikat sarongs, very nice!
The restaurant is ok, food is nice but but nothing special, but the service makes up for that big time!
The receptionist, Joseph, has the nicest smile on the island!
All in all we had a lovely time, and I hope they will not change too much with time.

My husband and I stayed there for 1 night in July 2012 in the Honeymoon Suite Bungalow which is really fantastic! It is at the western corner of the hotel ground and it overlooks the sea; it is built with coconut wood and has lovely rattan and coconut wood furniture; there’s a large canopy bed with mosquito net, AC (though not very strong), ceiling fan, refrigerator, lots of storage space, a lovely balcony with armchairs and table; the bathroom is very large and comfortable, hot water is provided by an electric water-heater. Sheets, bath towels and beach towels are of good quality. There is free wifi at restaurant, beach bar and reception. We had lunch and dinner at the restaurant and it was really good and not expensive. As we left early in the morning, they gave us a “breakfast box” (only 2 slices of bread, 1 slice of cheese and 2 bananas!!). The beach is good but not something to dream about!

If you are looking for a easy going, friendly and chill out place to relax in front of the sea.....this is the place for you. Nice grey sand beach, super friendly staff , good breakfast and very clean comfortable bungalows by the sea shore. Also we went to do a lovely boat-snorkelling trip around the nearby islands for a reasonable price (20$ per person - we were 4 people). Be aware that the resort is 8 km from Maumere so you will end up dining here most of the time. The food is decent but don't expect a professional service. It can be slow at times.

This hotel was better than I expected given the mixed reviews. I recommend it, but with a few cautions.
My first caution is this: do NOT go out of your way to head to Seaworld thinking exotic resort, stunning beach, awesome snorkeling.... we actually met a family who had flown in from Bali for two days especially having heard how good the snorkeling is. It isn’t! There are some nice corals if you swim out a hundred or so metres, but the fish are fairly sparse. The beach is actively net-fished by the villagers every evening, which probably accounts for why there are not millions of fish. What fish are there are interesting, but few compared (for example) to Amed in Bali, and not a patch on what can be seen on islands around Labuan Bajo or Riung. I’m sure, if you were into diving or wanted to take some snorkeling boat trips, you would see more - we didn’t do that. As for the beach, it’s a greyish pebbly thing that won’t get Australians excited. It’s pleasant enough, but not spectacularly beautiful.
If you are passing through Maumere, though, Seaworld makes a great place to spend a few days. It is genuinely peaceful and relaxing. During the day you might almost think you were alone, and yet the place was fully booked. There was plenty of room for my kids to safely go exploring. The grounds are well kept with lots of good shady spots. The beach bar is a top place to be during happy hour (4pm-6pm) and sunset, which can be very pretty.
The staff were excellent. There are a number of Indonesian staff who speak excellent English, including in the restaurant where the young man in charge there has a bachelor’s degree in English. The place really had the feel of being well-managed. Everyone really went out of their way to help us and make us feel relaxed and looked after. This was from the more senior Indonesian staff, the German owner and the young work experience people who were delightful. Seaworld was one of the few places in Flores where the high school work experience kids really did seem to be being trained at least in some form (coming out to listen to experienced staff take orders in the restaurant, for example), rather than just being used as free labour as seems to be the case everywhere else.
The food in general was good. We stayed four days and sampled most of the menu. One exception was the pizza. I imagine the person making it had never seen nor eaten a pizza as the pastry was almost an inch think and kind of wet. Steamed in a pan under a lid was my guess.
Free WiFi is available. It was good enough to watch the Hawks beat the Magpies (Australian football) on my laptop!
I also liked the fact that they would refill water bottles in the restaurant without charge.
We thought our room was hideously expensive ($90 USD), but that’s because they were fully booked on their cheaper rooms and we had to take a fancy room. What we got was way too extravagant for us. Two bedrooms, an indoor lounge room and a front porch lounge room. It was really very tasteful and nice to be around. We also got a fully cooked breakfast for four people included. So while it was expensive, it was probably not enormously overpriced for what it was.
One big negative for me... The presence of two white monkeys in 19th-century-style cages. I really, really hated seeing that. Maybe being white, they would not survive in the wild... maybe there was a good reason for having them there, locked up for life.... if so, would love to have seen something to explain... It bothered me the whole time I was there.
