We spent one week at this NH in late Oct 06 and found it very comfortable. The decor is contemporary, the room was nice and very clean, comfortable bed. The staff was helpful and the location is good, very close to Puerto Madero (great restaurants) and to the shopping in Calle Florida. What I liked the most was the breakfast: a fantastic assortment of pastries, cakes, fruits, hams, cheeses and warm dishes, really really good!
The only problem is that it on a street with a lot of traffic, but we had a room high up and noise was not a problem.

NH is just ok.

I had some potential bed bug issues.

The location is not ideal, taxis are a problem.

The staff is very aloof. But, the breakfast buffet is built into the room price and is nice.

Best perhaps for business folks, not vacationers.

Stay in Palermo !!!!! Trust me.

We stayed here a total of 4 nights. The loby and bar are attractive, with modern furnishings. The front desk, while not effusively friendly, was very efficient and organized. The room we had was on the small side, but nicely furnished. We had a tiny but cute balcony over Av. Corrientes which was also nice. Buffet breakfast was decent. Location was a mixed bag. On the one hand, it was within walking distance of the major tourist sights and Puerto Madera (with all of its bars and restaurants) as well as a subway station, but the neighborhood felt very commercial overall. You will need to get a taxi to go out to Recoleta or Palermo as well.

The NH Jousten was a very friendly place to stay although the locaiton is not great for tourists. We had a nice corner room with many amenities. The staff was very helpful although the front desk clerk is a bit of a sourpuss! We did get accosted by pickpockets outside the hotel in broad daylight. They sprayed some goo on us and made us to think that it was bird excrement. Their trick did not succeed though!
