We arrived late in the night (around 23:30) and were welcomed by Marcelo, a very friendly guy who showed us around the apartment and explained us the do's and don'ts of moving around Buenos Aires. The apartment itself was adequate; small but with the features we needed. It's located in a good area, on walking distance of a an area with lots of restaurants, bars and shops.

The first day we were there the light in the bathroom broke. Ralf himself came down and fixed it for us in no time.

All in all we had a very pleasant stay in a nice neighborhood. Recommended.
