Sergio is realy good and easy to communicate with. He answers very fast and takes care.
The apartment is close to train station, underground and also to all other local transports.
The kitchen is well equipped to make yourself coffee and breakfast - rather difficult and less well equipped should you actually want to cook something. But there are plenty of good restaurants around. So for a student or a young couple who just need a simple apartment for a few nights, this is absolute fine.
There were some problems with the key and the lock - but i think this can and will be fixed and with a little bit of improvisation, it all works fine.
