Overall a very good flat with good price for value.
We stayed in 3 people for 3 nights. The apartment is new, it has a large living room with a sofa-bed and 1.5 bathrooms (one without shower), which is very appreciated if you’re staying in 3/4 people. The location is very good as well, at the center of chueca. Check-in has to be done at their office at 16:00-19:00 if you don’t want to pay an extra.
