Sergio was very responsive and made sure there was some one to meet us at the apartment, who was extremely friendly and helpful.
The apartment itself is small but well distributed and super cute. It is very well equipped and has everything you need. The bed was very comfortable and while we didn't use the kitchen, it provides everything you need.
There are only 2 points that we were unhappy with, all of wich are not Sergios fault but should be noted:
The walls in the apartment are paper thin and we could hear the neighbours baby all night and all morning as well as the people upstairs.
Also the apartment is on the ground floor and only has one window, as it was a bit hot inside we cracked the window but unfortunately you can hear every noise on the street.

Other than that, it is very well located and everything is accessible by foot. There is no free parking on the street on weekdays so we found payed parking nearby in a garage that you can easily walk to.

Overall we enjoyed our stay, would have enjoyed it a bit more with better sleep ;)
