This is a great place to stay in BCN. It's in one of the best neighborhoods, close to the center, but still more quiet than other areas of the city.
The apartment is spacious and has lots of natural light, but doesn't face the street so you don't have the noises (it's a busy tapas area). The bed is comfortable and the shower has great pressure.
I stayed for a month working in the apartment and the internet is very fast and reliable. Also, it's easy to communicate with Jan and he was very helpful with any requests. I truly recommend the place and will stay again if I come back.
