We had a very nice stay at Tina's place. She lives in a nice and cozy little apartment in a very quiet neighborhood. We had no problems sleeping with open windows since there was only very little street noise. Tina herself was also very considerate and easy to live with. Everything was clean and nice.
The metro is only 10 minutes by foot and there is a bus station even closer. We had absolutely no problems getting into the inner city.
You should mind that you cannot lock the bathroom door but there is a mutual understanding that when the door is closed the bathroom is occupied. So no problems there.
The parking situation is a little bit adventurous. The public parking is at the end of calle harmonica roughly 100 meters away from the apartment. Google Street view shows you what I mean.
If you are allergic an important info might be that there lives a cat in the apartment.
We had a nice stay here and I'm sure you will too.
