The apartment is great, the roof deck is cool and the view of the busy street is nice. We loved the little tray of treats, and the provided toiletries, they were both very nice touches. The automatic locks were also super cool and very convenient! Really nice to not have to carry keys around and worry about losing them. The bed is very comfy, and the decorations were nice. We would stay here again now that we know how check-in works: you have to enter your document info (passport, driver license or such) on a separate website and "register" all guests there before you are given an access code for the automatic locks. I recommend you register before leaving your prior apartment if your phone needs WiFi like ours did, we ended up stuck waiting at a restaurant with WIFI in the square until it was complete, and it was a bit of a hassle.
To echo the other reviews a little, the shower curtain didn't cause us any real problems, but cutting it shorter at the bottom would be an easy fix to the complaints. Or putting in a clear one. I really liked the drama of the black curtains, until I couldn't quite see what I was washing. But it really wasn't a problem! Neither were the many and narrow stairs, but this is not the place for you if you have stair-related mobility challenges. There is no lift. We liked the stairs for a good post-tapas workout. The location is truly excellent, unbeatable!! No easy parking, but that's the area. We will definitely book here again if we can.
