This hotel seemed to us to be an old resort that probably used to be a destination in itself, but is now, for most people, just a two-day stopover while visiting the falls. There is a feeling of "faded elegance." The best part is the grounds, which are spacious and well-kept, and include a lovely pool area and beautiful nature walk that takes you down to the Iguassu River. The rooms that once might have been upscale are now clean but basic; they probably haven't been significantly upgraded in ages (if ever). There is new carpet in all the hallways, which was nice, but always people smoking in the lobby.

I think if you don't expect too much from this hotel you won't be disappointed, and will be pleased with the location - it is really nice to be able to walk to the Brazilian falls and to be conveniently close to the airport. We ate two breakfasts and one dinner there, and the buffets were fine for a family with two teenagers.

We picked this hotel due to its location which did not disappoint, however the hotel has beautiful grounds but the interior is all dark giving it a dinghy feeling. We had read previous reviews and seen the photos so we knew what to expect. The bathroom was OK but the bath itself had marks in the bottom of it. Our view out of the room was another building which was only approximately 4 foot away, together with a dripping roof all night. The bedding also looked very dated giving the whole room a dull feel. As we were only here for 2 nights it didn't matter too much however if I was staying longer I would definitely pick another hotel. The staff were OK and there was a tour advisor on hand in reception who was very helpful in craming in our requirements. She arranged for a guide who was very nice and arranged for our passports to be stamped in Argentina (not something always done because of the visitors to the waterfalls in either country). One good thing about the hotel was that it was only 10 minutes from the airport.

We stayed at this hotel for three nights.
The one major hiccup was the standard room. The hotel itself has a lovely swimming pool, grounds etc and pretty good facilities but the standard room was truly appalling.
We tried several of the rooms and they all stank of cigarettes smoke. The room was also not only small but the condition of the shower/hand basin was poor and in desperate need of replacement. There were also no plug sockets/no hairdryer or shaver socket in the room. Having travelled around the world this is the worst "4* star room we have ever stayed in - more like one star.
My wife in particularly was upset over the standard of the room and as a result we were forced to upgrade to a better room (at a price of almost £20 a night!!). Though small it had been modernised and was up to standard.

First the positive things:
We liked the large pool-area and also the breakfast-buffet was fine. (although we saw better ones on our Brasil trip). But the variety was good enough for us and everything was fresh.
We liked also the very close neighbourhood of the National Park and the Birds Park, which I recommend both.

The room was shabby, oldfashioned, obviously it hasnt been renovated since at least 20 years, the mirror was broken, the wardrobe smelly (as the room in general too) and there was not a single chair in the room !!! But the bathroom was the worst of all, simply disgusting and tiny tiny small. Everything rusty and extremly worn-down.

As I heard from Brasilians the most hotels in the Iguacu area are oldfashioned and worn-down, as the tourists still come there because of the falls. But we saw a few new hotels under construction along the Ave. das Cataratas. I therefore recommend to make sure to check the hotel age before booking. I would never return to San Martin again.

Be aware of the tourist desk in the hotel, the guy there is nice and gives good information even without buying a boattrip f.e.; But the woman trys to sell things people doesn't need oder can get in the National Park for half the price!! As we were in the middle of nowhere we had to book at least the transfer to the argentinian side, which was really expensive. But there's no alternative unfortunately. Taxis are also very expensive in that area. But I recommend to book the rest (boattrips, safari-trips) in the National parks, as it is cheaper there.
