We stayed 2 nights in Room 307. The hotel was very simple and I would rate this a two-star hotel. Unfriendly man at check-in (he was not focused on our check-in but kept looking at his phone beside him). The room was very simple, with two double beds. The worst part was the "balcony" it was something you had to step up into and WITHOUT steps (we stood on our flimsy plastic chair to get up) - a total safety hazard and so weird. Horrible small bathroom with very tricky shower, we could never get the water temperature high enough for our shower. The breakfast we paid for was horrible, there was barely bread or a good hot cup of tea. If you came down late, everything was gone, very little replenishing. The room itself had good A/C but the bed was old and well used. The one good thing about this hotel was that it was directly across the Bus Terminal (where we took the bus to Iguazu National Park, and the airport). The second good thing was that you could easily walk to MANY restaurants close the hotel.
