Me and my girlfriend had a wonderful stay at Maria's apartment and I would definitely recommend it to anyone who's planning to explore the amazing city of Buenos Aires while staying in San Telmo. The apartment is equipped with all the stuff one might need (personally, I missed a micro-oven, but this minor thing could not be considered as a disadvantage), Wi-Fi connection is pretty good, and the neighborhood is rather quite and safe. Moreover, San Telmo has a lot to offer, and Maria's place is quite close to everything. Again, I would certainly recommend it with no hesitation.
