Our overall expericience was great! Tomasz is very kind, replied quickly and gave us information on how to get to his place easily. We were welcomed by Maria, a friend of Tomasz, who was very friendly and gave us a little tour of the appartment and some touristic information. We had some problems with our door the first night and couldn't get it, so Tomasz came immediately at 11PM to help us out. That was the only time we saw him but he was nice.

The apartment was clean, like advertised, we had access to a kitchen, 2 showers and 2 toilets. WiFi worked great too. The location is good, in between the Sagrada Familia and the Arc de Triomf, 10-15 minutes on foot from the center of Barcelona and next to a busstation. The only downside of the room is that is had a window to an indoor court, so no view on the street. The little bonus was the cooling fan that Maria gave us, which was greatly appreciated with the warm weather of Barcelona.
I gladly recommend this room for a couple visiting Barcelona.
