We had a great time in Barcelona. Luis' place was great- it was slightly outside of the main tourist area but about 5-10 min walk to metro and 2 stops for main area. Plenty of good food and supermarkets right outside apartment. The only things we had trouble with was the apartment is very noisy-we could hear the neighbor sneezing in the night and there is no real windows to the outside so not much fresh air or light coming in. Besides that we had a nice stay.
