I was there for 4 nights and just loved it! The service was friendly, the breakfast was good (but be careful not to be late: when the time is over, they don't admit people even 1 minute late and start putting away the breakfast food!), the location perfect (2 blocks from the Puerto Madero restaurant area and 2 blocks from the Galerias Pacífico and Calle Florida!) and what impressed me the most: the building!!!
It is totally renewed and very charming, classical decoration and cousy rooms! You can tell it is an antique building because it is charming, the elevator is small and the façade still has the reed brick from old times! Highly recommended!

The NH Lancaster is located on a busy street, but is in within walking distance to shopping and sites. The rooms are small, but have everything you need for a comfortable stay. The breakfast buffet was basic, nothing special. A few blocks from the hotel is Florida Street, a pedestrian mall stretching from Plaza de Mayo to Plaza San Martin. Close to the hotel on Florida Street is Galerias Pacifico, an awsome shopping complex. Even if you're not in the mood to shop, you should stop in and be impressed. Not too far from the hotel on Av. Cordoba is the refurbished dock area, Puerto Madero. Once the main shipping dock, the dock area has taken on a new life as a hotel and trendy restaurant area. Also you'll find the Women's bridge in Puerto Madero.

Very well located 2 blocks from Florida Street and Galerias Pacifico. Few blocks from Puerto Madero and 9 de Julio Ave.

Located on Cardoba St and Peatonal Reconquista where you can find great Pubs and Restaurants.

Well localized hotel near Buenos Aires Downtown!

You have everything in a walking distance diminishing your costs with taxis.

This hotel stays in the begining of the Cordoba Avenue, very near the revitalized port called Puerto Madero! Make fair use of it's localization by going on foot to all restaurants nearby!

PS: Don't forget to try some "facturas" in the breakfast.
