I loved staying here and would absolutely do it again. The apartment is exactly as described and the location couldn’t be better. It’s in a great neighborhood that is walkable but not too close to the ramblas. One thing to note is that the entrance is on a corner. The cab driver dropped us off at what we thought was the right location (it was the entrance next to the adjacent address) but we actually had to walk around the corner. This cost us about half an hour of waiting in the wrong spot to check in.
There were a few minor annoyances- there is no trash can in the bathroom (not sure why) and we ran out of toilet paper halfway through our stay so we had to go buy some. Also, there is no place to leave your bags after you check out so we had to walk around parc Guell with our luggage. Regardless, the host was very responsive and I highly recommend this spot!
