I did not meet Carolina, but was checked-in and out by Alejandra, her welcoming , nice and reliable neighbour.
The house is as you see in the picture: cozy and stylish, equipped also for long periods. At first floor you will find the living room, with open kitchenette and extra room (Carolina's, I guess). The kitchenette is convenient and fully equipped, for those who like cooking vegetables or other stuff bought downstairs at the S. Telmo market. Your room is located upstairs, reachable by a steep wooden stairs. The room is rather big and the bathroom is embedded in it, separated by a sliding door. The terrace is super. In the period I was there, nobody else was at home, but in both cases you can use both your room and the living room/kitchenette.
Very conveniently located, San Telmo is probably the most pictoresque neighbourhood in Buenos Aires. I have loved it, but be careful with your pursue: it is a turistic area and stealing professionals might be around, even in calm corners. This said, the house and building is super secure, so you won't have to worry about your stuff there.
Definitely I would love to stay there again next time in Buenos Aires! Thanks Carolina for sharing your house with us.
