We had an excellent stay at Adriana's. The apartment itself is incredible. Very spacious, beautifully decorated, and set up with everything you would need for a long term stay. The location is perfect. You are walking distance from a lot of key destinations: the BA sign, the San Telmo Market, the Recoleta cemetery. When it is too far to walk public transit from the apartment is incredibly accessible. There is a bus across the street that comes almost every 2 minutes and Adriana sets you up with a sube card to access the bus and metro.
Our stay was lovely and I would definitely book here again :)
