We met Alicia in front of the building and she showed us around the apartment and gave us tips for a good restaurant. The apartment has all basics you need, has a good size for 4 people and is nicely decorated. The location of the apartment is superb! You can reach everything on foot.
As it is located at a lively square it can be loud during the night. But as we had our windows closed it was no problem.
TIp: take a taxi from the airport as it is only 30 Euro and you safe time compared to metro.
