Ana's flat is very sweet and has many things going for it. the neighbourhood is full of life - loads of restaurants and plazas full of interesting people but it is also very quiet late at night when you want to sleep.
The place itself is very comfortable - the AC is quiet and effective and the main bedroom is nice and dark so you can sleep late if you are feeling the Cava from the night before. The only thing we missed was the WiFi but that is also nice to get a break from too sometimes.
Dealing with the keys etc was smooth - though watch that you read the correct address in the emails we ended up at what I guess is Ana's business and not the unit so just watch for that.
Overall I would totally recommend the place, we really enjoyed being there.
