We stayed several nights and greatly enjoyed the location and functionality of this apartment. The Gothic quarter is a one of a kind locale with good access to public transit, restaurants, Las Ramblas, parks, and waterfront. The building is safe, several stories off street level, and outside the range of noise and street traffic. Rooms were clean and well decorated. Wifi, hot water, laundry, and kitchen all worked great. The other guests in this shared flat were polite and quiet- either way, all public rooms have interior locks and a padlock for your private bedroom. Would stay again if visiting Barcelona!
