The flat is exactly as described on the pictures, no bad surprises and the bed is very comfortable after a day of exploring the city.
Pina is very friendly and even though she does not speak English we did not really have communications issues. When we arrived crackers were waiting for us and there was water in the fridge. And since one of us was having his birthday we were treated with a cake, a bottle of sparkling wine and flowers!!
The location is not central and not close to a metro station so expect a fair amount of walking (or maybe try to use the buses, which we did not do). There is a small supermarket just around the corner and quite a few bars, cafes and restaurant in the neighborhood.
