Well where should I start!! That was absolutely amazing to stay at Matias' place, not only because the apartment and the room are superb but also because Matias and his girlfriend are just super friendly and make you feel home once you cross their door!
They are generous and helpful and we don't have to worry about getting lost in BA, Matt has all the infos you need.
The apartment is located right in the center of BA to a walking distance to pretty much everything.
Definitely recommend this flat!! 10/10 !!
