It was a very nice apartment, perfect for 2 families (8 total). 4 bedrooms, a well-stocked kitchen, a washer/dryer (so useful for longer trips), a comfortable living room for relaxing as a group. Carlos was a very friendly host, who made everything very easy for us. As an example, he sent us an extensive list of recommendations for local restaurants and attractions. There are many restaurants within a few blocks of the apartment and a terrific bakery just around the corner (from which we got breakfast every morning). The location is very easy to get to from the airport (RENFE train to Passeig de Gracias + 3 block walk). It is walking distance or a short cab or metro ride to most of the major sights in the city, while being a little away from the most touristy streets. The apartment is 4 floors up with a small elevator, which is sufficient for sending up luggage but maybe not for all your trips up/down. We often used the stairs, which might be a consideration for less fit visitors. 2 of the 4 bedrooms overlook the main street, which has a decent amount of traffic noise. If you are not used to urban noise at night, you might want ear plugs. The other 2 bedrooms away from the street were very quite. All bedrooms were very good at staying dark when we wanted to sleep in late (with jet lag from America). Overall, we were very happy to stay here.
