Our stay here was perfect!
Location: It was a great spot in the city to both get to landmarks and the conference we were attending as well as walking in neighborhoods to find and experience local restaurants and get a true Barcelona experience. The area was great and we never felt unsafe even at night.
Apartment: Very Clean! The place was perfect when we arrived. Everything you need. We had a 1-week stay so the washing machine and Iron were great to have. The bathroom is excellent and updated. The apartment is up just 1 flight of stairs so it was easy to get the bikes that we rented to get around the city in and out. A holiday fell while we were here so we spent one evening sitting in the window like a balcony and watching local kids shooting off fireworks in the courtyard/park below.
Overall it was a great experience and I would certainly stay here again.
