Carmen's apartment is a comfortable place to stay. The host was extremely friendly and responsive to our needs. Despite its excellent location, which is close to almost everything, it is a bit unsafe.
Our only issue was with an old woman who lives right below the apartment. Even if we don't put music on, she always complains about the noise, just because we're walking/talking at midnight. We were not aware of that, and it would have been helpful to know before booking since we were on vacation, and didn't want to be concerned about making noise (of course, we didn't have a party, we were simply "living" there).
