Wonderful! Barcelona is a fabulous city and this is a great place to stay! So close to everything -- walkabout to many sites and with easy access to many transit stations as well.
We had a car which we parked in a nearby garage. Many of the side streets in Barcelona are very narrow, but one of those narrow streets right next to the building has a parking garage so the access was quite close.
The apartment itself it spacious and comfortable. We found everyone friendly. This is a great place to stay!
