The place is perfect, we didn't met Ramfis and Carolina but his friend Dieter received us, he's really nice and answer all the questions we had. The apartment is in a really nice place, you have 2 supermarkets near to the place and the tram is literally in front of the apartment. It's a perfect place to stay with your family.
Ramfis and Carolina were always in communication with me, they are really nice hosts.
