What a really great place to stay. You step off the street, out of the traffic, bustle, day and night life of San Telmo, into complete serenity. Not because of the wonders of modern architecture - double glazing and the like - but because they built solid houses back in the 18th Century. As many reviewers note, the accommodation in this small hotel opens onto a couple of peaceful courtyards. And those rooms are varied. Some are small apartments on two floors, others a simple en-suite bedrooms. I had a fridge, a coffee percolator, kettle and sandwich-maker, and wi-fi. As well as the room, there is an elegant sitting room to the front of the hotel that has a computer with internet access.
One of the real blessings of this hotel is that it is shared with the owner, a delightfully interesting and cultivated woman. She has shedloads of information to share ranging from advice on restaurants to a detailed understanding of the socio-political heritage of both Argentina and Latin America in general, all of which is shared without a hint of pretentiousness. You'd go a long way to find someone as obliging, genuine and helpful.
The hotel has a "lived in" feel to it. So don't expect shiny stainless steel fittings and all the characterless hand-me-down chic of so many hotels. This is a place where people live and that people love. I don't live there, but I loved too it.
