Since I contacted Ruben the first time, he was very kind and after the booking he provided me the rules of the house as well as some suggestions for visiting the city.
The apartment was exactly the one show in the advertising. I met Ruben the first day, he explained me how to manage the house in order to avoid misunderstandings. The apartment was comfortable and well-located. In 5 minutes you can be at bus 48 and tram 10 stop, and from there, in only 10-15 minutes you can reach the city centre.
Definitely recommended!
