My wife, myself and our 23 year daughter stayed in this 2 bedroom apartment for 5 nights.Our communication with Vincente, the property manager for ClickandFlat,was incredible. The apartment had air conditioning which worked extremely well, a washing machine with a built in dryer (the only dryer we had in over 3 weeks in Spain), a dishwasher and everything needed in the kitchen to prepare meals. I learned that there are over 10,000 taxis in Barcelona so it was very easy to get a ride to any of the sites that we wanted to see. We could walk to quite a few including Casa Mila, Casa Batlló (house of bones), Casa Vicens, the Gothic quarter. There was a supermarket about a 5 minute walk away, a fresh food market about a 7 minute walk away and many restaurants in the area.
Vincente was very attentive during our stay and he was able to provide us with additional dishwashing/laundry soap, coffee, towels, etc, along with sightseeing and restaurant and shopping options.
Overall our stay was excellent and we would definitely recommend this apartment.
