Gabriel's place is really very nice - comfortable, very close to many restaurants (La Popular, 30 meters from the building, was my favorite: nice food, waiters with whom you chat as if you were a regular costumer, while in the background you listen to classic tango all night long. By the way, if you are for of tango (listening, dancing or simply watching normal people dancing), there are some very nice milongas nearby. If you want to have a feeling of what it means to be a porteño, San Telmo is one of the most charming places to stay, and Gabriel's place will please you, for sure!
