Really nice and very comfortable flat. I brought my extended family for a short break in Barcelona, a total of 6 people, and they were all very impressed with the accommodation. Importantly, it is very close to two Metro stations - Rocafort (red line) and Poble Sec (green line), so you can reach most of the main attractions of Barcelona in a heartbeat. This part of the Eixample (the neighbourhoo) is pretty quiet, with lots of small shops you can buy food from if you need to.
Juan Carlos is a fantastic host, a really nice guy, and keen to help (JC, the paella at Elche restaurant was great!!).
All in all we could have not asked for more, so thanks again!
