We had a great stay at Lucy and Cais lovely little apartment. The neighborhood is very charming and everything is within walking distance - restaurants, shops, museums, hillsides, waterfront etc. In fact, we walked all over the place and never used any transportation within the city. Our two year old also enjoyed the place and the friendly neighbors. And there are lots of nice little playgrounds all over the city. Lucy and Cai were great hosts who made sure everything was in order. And they were very flexible and helpful when our flight was delayed. We would come back and stay some other time. Only minor thing that we had to get used to was the noise from the street. But this is probably a general condition when visiting Barcelona. If you're a light sleeper bring earplugs and you'll be fine :-)
