Great apartment in pleasant street, with a roomy feel. Really comfortable seats in the living room and a nice dining area. The flat generally felt quite modern except perhaps the fittings in the kitchen.
So far as location went, this is a great place to stay, perfect location for getting about with easy access to the Metro stations for Diagonal and Passeig de Gracia. Do try to get the train to the airport from Passeig de Gracia, it is really easy and cheap!
Alex was really communicative and always replied to emails really quickly. Check-in was really easy too.
Would stay here again for sure on another trip to this lovely city.
