This was a nice studio to stop in for a short stay in San Telmo.
Apartment: the place itself is very nice and clean. It's a nice fit for two people, with a bed, closet space and a small kitchenette. There is even a small balcony for enjoying your coffee during nice weather. It gets great sunlight in the mornings.
Reception: I appreciated the 24-hour reception and the maps and tips they provided. It was quite confusing at first on how to get in, and I didn't receive any instruction from Rob (the "host") on that front. This is in a set of apartment buildings, which makes if feel homey and modern.
Location: The San Telmo neighborhood has some great restaurants and bars, and we also wanted to be close to the Sunday market (which is a must-see!) San Telmo can also have some seedier areas, and this street can seem a bit unwelcoming at first, especially late at night when it is quiet except for cars zooming by. I didn't feel that the street was dangerous, but it is a place that you want to be aware of where you are and where you are going. When in doubt, head for Calle Defensa, the main street and a busy spot two blocks away.
