We stayed in Hernan's flat for our wedding weekend, so the family of 11 wanted to stay together. The flat was perfect for what we wanted. Very spacious, clean and with everything we would need to hand. The building itself is really pretty and the location is just perfect in between rambla de Barcelona and passeig de Gracia, full of restaurants around and to walking distance to the plaza de Cataluña. The communication with Hernan was very good from the beginning and didn't have any trouble to contact him.
In general we have an amazing experience in the flat, and would definitely recommend Hernan's flat.
