I enjoyed staying at Carolina's place. She was very warm and welcoming, and helped make arrangements for me to get into her place when she was at work. She offered suggestions for places in the area to see and visit, and was available to answer questions when I had them.
The room is nice and the private bathroom is perfect for a solo traveler. I was pleased with everything and was thrilled at the location. 5-10 minute walk to metro, restaurants in the area, yet it was a pretty quiet street. I would recommend this place to anyone visiting Barcelona. Carolina's place is great!
