this place is really nice and I enjoyed staying over there. The place is just right for one to two persons and the location is perfect to explore Buenos Aires by walking around. Also there is a little guide book with recommendations. I didn't have the time to try all of them but the ones I've tried were all very good.
Only one thing that might need to be optimize - the Internet / wifi connection wasn't very stable but Manuel already told me he will double check with the Internet provider.
