We would recommend Pedro's place, although on foot it's a bit further away from downtown (20-25 min up and down hills), but there are great restaurants in the area, and easy to park on the street. It's in a quiet area, although you may hear the neighbours come and go sometimes.
The flat is great, very stylish, with only a few minor improvement points.
We would recommend this place, it was great to come back here after long days of sightseeing.
