Booked into Hotel Nogaro for 2 nights after being on the backpacking trail for 3 months. The first room I was put in (on the first floor) was noisy as it faced the street and only had single pane windows. So I requested a change and was moved to the 2nd floor ... this room (Room 201) was an upgrade for the same price ... it also faced the street but it had a balcony with a double set of doors that kept the noise out.
The view from the balcony was great and the bed ... ohh, I still dream of that bed ... it was the most comfortable thing in the world. My initial intention had been to stay just one night but that bed seduced me into staying 2 nights :)
The breakfast was also terrific and set you up nicely for a day of city exploration. The hotel is in a great location as a starting point for navigating the city.
The only minor issue with the room was that there was a small leak in the bathroom ceiling above the toilet ... but that has probably been rectified by now.

I was part of a group of 7 people staying here for a week for a conference in mid-November 2011. The location is great - just off the historic Plaza de Mayo, at the hub of the subway system, around the corner from the Sunday market in San Telmo, etc. The Cafe Victoria down at the corner has a terrific lunch menu. The hotel is a remodeled old "classic" with new bathrooms, nice lobby, high-ceiling rooms, etc. The staff could not be more accommodating, giving directions, lending us converter electric plugs and umbrellas, etc. The included breakfast is adequate but not great.
However, the wifi connections are totally inadequate. We changed rooms from a high-floor deluxe room with a beautiful view to a low-floor, rather spartan so-called "suite" just because there was no wifi at all on the high floors. On the lower floors it is somewhat spotty. Others in our group reported that the wifi would only work in the bathroom, etc. I noticed lots of people using their laptops in the lobby and dining room, so I imagine the problem is fairly universal.
Given the price - moderate for Buenos Aires, but still over $160US per night - reliable wifi ought to be included. Don't stay here if you need regular access to the internet.

the hotel lobby looked nice but the bedroom was very old and no maintenance work was probably ever done.

The lobby gives a false feel to the infrastructure of the hotel. I went to my room and first noted that the hallway lights on my floor were mainly burnt out. My main concern was no Internet for first few days. Every day I was told that the "technician was coming or came, everything should be working, etc". It was never fixed so I assume it to be a lie as I heard the same thing said to others after I informed the front desk that it was still not working. Only Internet in the lobby works so I had to move on my 3rd day to a room on the 1st floor. I can not be on a business trip without Internet! First room was old...second was more modern but smaller. Spring at Nogaro means no heat or air conditioner so if it is a hot day don`t expect to turn on the AC...even if your room is 75+ degrees in the room! Today it is cold but same as the Internet "someone is working on it". Service is very average, facilities are average, etc. There is a "congreso", the hotel is packed and the restaurant does not serve food! The bar serves sandwiches. There are 2 cafes on either corner but I heard a guest say that she was robbed there the other day. The area around the hotel is not safe to wander around in at night and if you do, you should not carry valuables. This hotel and this area are equally not worth the price. I recommend looking for other options if possible!
