As a first time visitor to Barcelona we were not sure on where to stay. We lucked out with this great location to everywhere we wanted to go and still a quiet neighborhood feel. We loved the nearby plazas non-touristy for dinner and drinks. Our son loved having his own private room on the other side of the apartment. We were never bothered by any noises at night. The small elevator was handy for our luggage (the apartment is about 3 1/2 flight of stairs to climb). We never needed public transportation during our stay and walked everywhere (with a kid) except a taxi to Park Guell. It took us about 25 minutes to walk to the Sagrada Familia.
The apartment is exactly as pictured and clean. We had everything we needed including nice details such as a hair dryer and a nice washer/dryer for a load of laundry.
My only suggestion is to provide a few coffee pods to get guests started as we are we really need our morning coffee! We never did take the time to figure out the coffee system or hunt done the right pods at the markets, so we just grabbed some on the street.
Thanks for the great stay!
