Bernardo was a very nice and easygoing host, and we had no problems retrieving keys. We chose to stay at his place because it was very close to our son's apartment. But we discovered that it was a very pleasant neighborhood (and "trendy" for those who like such things). It is quiet with not too much traffic. It is very leafy, with lots of trees (though this can make for dark pavements at night). It seems very safe. There are lots of nice bars and restaurants. On the practical side, the apartment is not too far from several subway stops (10/15' walk). Also, there is a good supermarket just around the corner. The apartment is an ideal place for a couple (we were three adults and it was a bit of a squeeze).
