We lived in this apartment for 2 months and it was great. In the apartment you can find everything you need for a living.
The location is excellent, close to the subway, supermarkets, bakeries, bubble tea places:). Close to Passeig de Gracia, where you can find a lot of restaurants, shops, cinema(they have movies in original language). Also Parc de la Ciutadella is nearby, where you can go for a walk with your dog.
Highly recommend to stay at Varda's place and explore Barcelona from there.
