There were many great things about the flat, which is why we booked it for our Barcelona honeymoon. The vibe is cool, the location is great (few blocks from Sagrada and two blocks from Metro). Loved the views on both sides of the flat, kitchen was usable and concrete was cool.

However we left the flat two days early, primarily because of three problems. The bed squeaks. If you move or get out of the bed, you will wake the other. The bed is also small (maybe full size), though the size wasn't disclosed and we didn't ask.

Second, the water in the shower would randomly go from really hot to cold, without us touching anything. That made it difficult to get a good shower.

Third, there was construction next door at 8am. Not great for jet laggers sleeping in. That may be gone if you leave, but that wasn't disclosed.

There were some other annoyances. We were left with two crusty towels for a whole week. The hosts property manager didn't respond. The property was running out of toilet paper, and also you'll need to bring your own soap, shampoo, etc.

In the end, we left early and stayed at the W for a couple nights so we could get sleep and shower. The host checked the issues we claimed and denied the squeaky bed or water problems, so I guess it's your call.
