We stayed for 3 nights. The size of the Apartment for 4 People is very good. The location of the apartment is also very good: only a few minutes away from the metro station and many Restaurants/Bars are accessible in walking distance.
The apartment itself was clean. It was equipped with the bare necessities.
The lady at check in/check out does not speak English (only Spanish) . A translator app helps with communication. In case of problems/questions she was very reactive.
