Sonia was a great host! We had very easy communication, the apartment was as described, and the location worked very well for us. We arrived a bit before the checkin time, while Sonia was still cleaning. We were able to drop off our bags and get some lunch in the mall at Plaza España, about a ten minute walk away. (She had given great directions to the place — about a 30-minute, €2.20 bus ride on the #46 from the airport. )
The apartment met our needs completely. We were there three nights, and found buses and metro connections very convenient. Plenty of places to eat close by, but I heartily recommend Las Tasqueta Des Blai, about a 30 minute walk.
If we get back to Barcelona, I would definitely contact Sonia again!
