El personal eficiente Fernando el de Front Desk super servicial

Hotel needs a serious facelift. Old creaking beds. Room design lets light from bathroom shine on beds thru a glass wall. Breakfast… sometimes no scrambled eggs, sometimes no bread when restaurant opens; starts with previous day’s left over cheese balls.

Very convenient location, good price, very good breakfast. Bed is a little too small.

Excellent location, good breakfast

Great location close to dining options, bars and shops.

Breakfast was fresh. Lots of variety. Attentive staff.

Great location , modern clean rooms

Breakfast is not included

First time in Iguazú (and in Argentina) and I will definitely come back to Iguazú but as long as I stay at the O2. I could not have chosen a better place, a hundred meters away from the heart of town where everything goes!

A no-frills hotel that is reasonably priced and facilitates exploration of the near-by natural wonders. US $138/night, including taxes, fees. Good lookout from rooftop pool/bar of where three countries meet and the rivers feed dense vegetation. Good variety in breakfast buffet, which begins at 06:00. US $25/person/day. Great for people heading out early to explore the national park. Less packed after 07:00. Amenities are basic. Towels are thin and vary in color. Mediocre soap and shampoo. Small fridge. Lock-box. Staff are generally helpful. Location is close to city center. But you must walk past an area where sketchy folks sometimes linger. Hiring a guide with a vehicle is highly advised to access and explore either side of the park. Brazil requires an ETA (for Aussies, Brits and US-Americans) and that you walk into the office to present your credentials—coming and going. We saw both sides in one marathon day! Overpoweringly magnificent!

Comfortable stay

The hotel was clean. The rooms comfortable. Easy to get to the falls from the nearby bus terminal. Breafast is fine and the area is ok. Pool bar staff (or to be fair one pool bar staff was very rude). Rest of staff very pleasant. Rooms cleaned well every day. Good staff. An unfortunate incident at the end which marred our stay.

Good, but nothing special. "Instagram vs reality" photographs somewhat.

Great location

The hotel has a great location to the center of town. The pool on the roof is nice to have an evening cocktail or to lounge around. Remember it gets hot here so by early afternoon one has to hunker down in either AC or by a pool. Breakfast can be a bit crowded but it was good.

Breakfast is good. Staff are helpful. Good panoramic views from the rooftop bar and pool area. Good value for money. Many restaurants nearby.

Great location, upper pool deck with the view and bar is very enjoyable.

There is a gym and a pool, but I haven’t used them

Great for a last minute stay during the transportation strike! Friendly staff, good location, very affordable!

Clean room, comfortable
