Very well equipped flat. Kitchen all set for cooking and dining (and a nice tiny Spanish delicatessen shop is right across the road).
Great location close to Rambla with top tapas place, top pizza place and top Indian food just within 10 min walking distance.
Minor issues with cleanliness, which the host was eager to resolve.
As a possible drawback, no sun in winter (north-facing windows on a narrow street). Seems to be the case with most Barcelona buildings though, but may actually be an advantage in Summer so that you can enjoy some time on a nice balcony.
