We had a very pleasant stay at German's place. It is beautifully furnished and separated from the street by a courtyard, thus quiet and private. German was easy to reach at all moments, and his son was there to receive me late despite my delayed flight. The apartment is well located in Colonia Roma, a short walk from endless restaurant options as well as art galleries and cute small shops. The only drawback during our stay was that the hot water was fickle, but German was attentive to the problem and came by to fix it.
