I arrived at this hotel after having spent a week at a standard hotel in the Microcenter. The difference was overwhelming. From a very busy and chaotic atmosphere in the central downtown area, this little oasis was perfect for relaxing a few days.
I thoroughly enjoyed walking around the area. The hotel is located in Palermo Hollywood. A few minutes of walk will also take you to Palermo Soho, both being trendy nightlife areas, although this was not noticeable from inside the hotel. You will have to take a taxi or walk a few blocks to the metro to get downtown to the Microcenter, but the taxi ride should be affordable - max 25 pesos or about 6 USD.
The hotel staff was extremely friendly and attentive, but informal. There were fx no uniforms, which made me feel a lot more like home. The staff gave me their full attention throughout the stay and made me feel comfortable in their company - which is my number one criteria for good service and which is not necessarily accomplished by even the most expensive hotels. They went out of their way to make me satisfied.
Having said this, a few things must be mentioned. For example the minibar which was empty. Apparently they didn't have minibar merchandise in stock and had run out of its contents. I wouldn't have used it anyway, so it wasn't really a problem (and there was a 24h open kiosk just outside), but when there is a minibar in the room you should really be able to fill it even if it's not top season. Same thing happened with the internet access, which was free wi-fi, but they ran out of cards at my last day so I had to use the reception computer. Again, not really a problem for me, but I can understand if other people would be annoyed, and it does imply that they have some kind of logistical challenges.
Otherwise I have no complaints about the premises. The room was amazing, a stone room with a high ceiling and an open bathroom - very romantic for those looking for that (the actual WC was naturally in a separate room). The courtyard from which you entered the rooms, was very charming and with a wall-size replica of a Salvador Dali self-portrait - bonus points for that. The common room was cozy and nice and the breakfast was splendid.
I recommend this hotel if you don't expect 5-star luxury or immediate access to downtown areas, but settle for friendliness, a relaxed atmosphere and a beautiful part of Buenos Aires.
