The apartment was bright and sunny within a 5 minute walk of the metro and had everything we needed. Rosi greeted us on the morning of our arrival and not only showed us around the apartment but also gave us a thorough overview of things to do in Barcelona and where to eat. We stayed for 9 nights, took the metro everywhere and felt like the locals.
Average wifi speed in the living room is around 14mbs, and sometimes the signal wouldn't reach the bedrooms in the back of the apartment. So not a great situation if you plan to work. There was a minor incident with the water heater but Rosi helped us troubleshoot it and the hot water was back in a couple of hours.
Overall we enjoyed our stay and would recommend this apartment to others!
