Iza and David are amazing hosts. In the apartment you can find everything you could need. Even when I got sun-burnt there was an after-sun lotion which was very helpful:)
They responded to all of our questions regarding the sightseeing, the public transport etc. Also the apartment is very clean and has a very good location ( near to Sagrada Familia, Barceloneta beach and Parc de Ciutadella). Everything was really perfect!
