We spent seven nights at Oualie as part of a flight/hotel package (ordinarily not our thing, but we didn't have much time to book and it was the easiest way) so I don't know how much Oualie would charge for rooms alone. Airport transfers were included in our package; the Seamoss guys picked us up at the St Kitts airport and drove about 15 minutes to the coast, we hopped on a boat that took another 10 minutes or so (depending on climate and wind) to Nevis. We saw some passengers pay USD60 per person each way.
We were housed on an upper-floor room in one of the two-storey cottages and had a nice view overlooking the ocean from fewer than a hundred feet away. The room was large, clean, and plainly furnished. We did not get a four-poster bed as some guests have written about -- instead we were given two twin beds with somewhat lumpy mattresses. The linen was not changed every day, but they did change the towels and did a good job cleaning. There's a mini fridge, a ceiling fan, a/c, and a small tv with dozens of channels from the US, which was a treat. There were two safes in our closet, but both were locked and they never did find someone to fix them.
There was a balcony with screens all around to keep out the bugs. It's pleasant to sit up there, even when it's raining.
Beach towels are provided. And they had a British/UK adaptor to loan us.
The bathroom was clean. There's a hair dryer, soap and shampoo they re-stock regularly. The water was mostly cool, at best lukewarm, although by midweek we started getting warm-hot water.
It was hard going trying to pry the windows open, but it was worth it as there were very strong winds for the entire week. (Some locals said it was unusual, but everyone else seemed to think it was typical.) Strong enough that it wasn't pleasant to sit on the sand, since grains were getting everywhere. But there's a lot of nice green lawn to choose from, and they do have hammocks strung up in the shade at various points along the beach. Sandflies do live happily off visitors so beware, especially when there is no wind and especially at sunset -- which is early in January.
There are no hawkers or vendors on the beach as well so it can be very peaceful. A dive shop is right next door.
We had no issue with noise from the bar/restaurant, but we were a few buildings away. The food is not bad although somewhat repetitive. (Sunday breakfast is a buffet, and they do cook a pretty decent pancake. Waffles are also good.) We encourage everyone to try Gallipot, which is about a 10-minute walk away, heading south.
Transport is the only main issue. There are many buses (minivans with a licence plate beginning with the letter H, costing USD2 per person), but not on Sundays. A taxi ride to Charlestown will set you back USD15 each way for the 10-minute ride. So you're better off renting a car, but you'll have to purchase a temporary licence for USD25 and with the taxes and service etc, you'll end up paying around USD75 a day for a car that's being advertised for USD60/day. Still, it's worth it as all the restaurants are a drive away. (In addition to Gallipot, we liked Lime's on the beach, next to the Four Seasons, and Bananas up in the mountains although the owner is a bit snobby.)
Service at the front desk is somewhat erratic. Some folks are super-friendly, others not so much. But they all know their stuff and are generally helpful. There's a computer desktop in the reception area for guests to use. They helped book us a car rental and can organize excursions (or point you in the right direction).
Again, it was very pleasant, and the vibe is very relaxed (unlike what we saw in St Kitts), but I would warn folks that this is really a no-frills place for USD200+ a night (which I saw advertised somewhere), which should in reality cost USD100/night for what you get.
