I went to Buenos Aires in December 2007 and stayed there for 4 nights (3 + 1). The hotel is in the city center, on a walking distance to several places (oblisquo, casa rosada, congress, Florida Avenue, Puerto Madero and many others). The breakfast is great as well as the service. The rooms are also good but the view is bad if staying on a standard room (at least that what happened to us and to another couple).
We traveled to Iguazu after and left most of our bags in the hotel, coming back 3 days after. There was no problem. When we came back we got a bigger business room, with view to the main avenue.

I stayed at the Pestana in Feb 2007 for two four-day blocks, before and after a two-week trip in Patagonia. I was booked in via my travel agent, who got me a room for EUR 88,- per night, a price I could never match via any other way of booking.

The hotel is situated on Carlos-Pelegrini on the edge of the Avenida 9 de Julio between Avenidas Cordoba and Santa Fee: i.e. all of the Microcentro is within easy reach on foot. I had rooms at the back (10th and 12th floors) and , despite the proximity of the world's broadest street, there was no traffic noise even with the windows open - just the background buzz ot the city.

Both of the rooms were large (for Europeans), clean and in very good repair and the air conditoning worked well and was not intrusive. Breakfast was included and there was a well-stocked, tasty buffet, which was more than adequate.

The staff were very helpful and friendly and pretty fluent in English. It went without saying that I could leave my excess luggage locked away for the duration of the Patagonian trip at no additional charge.

This is the best hotel I've stayed in so far in Bs.As. and I can recommend it without reservations - with the possible exception of the breakfast coffee.

Thoroughly enjoyed out time in this hotel. It is situation on the main avenue, within walking distance of the pedestrian malls and to numerous restaurants. We walked to the main square, Recolleta and many other sites. Felt that we were in a safe area of the city. The room was quite nice and modern. The breakfast was very good. The staff was helpful and many spoke English quite well. Unfortunately the view from our room was not very nice. That was the only downside to this hotel. Would certainly recommend the Pestana for your stay in Buenos Aires

My wife and I stayed at this 9 de Julio hotel for six nights in early March and again for three nights at the end of March 2006 and had excellent experiences. The rack rate posted is $181.50 US, pricey but the location is extremely central for first time visitors and the window glazing such that on both street side and back side rooms street noise was not a problem. Our first compliment was that we were provided a room by 10 am on our first check-in after an overnight flight from North American, and on check-out before an overnight flight home we were given full access to their pool with showers, lockers, chaises longues, etc. The rooms are average size, the bathroom compact, but everything modern and clean (except the carpet which was badly spotted in both rooms). Our second big compliment was on our return when many staff welcomed us "home" and remembered our prior visit and special needs (tea not cafe con leche at breakfast). If this is in your price range, highly recommended.
