This flat is in a great location. A short walk to the underground station as well as a grocery store and restaurants. Very clean and comfortable. The check in process was very easy. We were actually late due to flight delays but using an electronic key allowed us to get in without a problem.
The loft is as described so do keep that in mind if you have mobility issues. I am 5'3" and could not stand up in the loft. That said, the bed was comfortable and if all you are doing is sleeping here it's not a problem at all.
The area is quiet and safe. We did hear neighbors that woke us up as we were trying to go to sleep but we also went to bed really early due to jet lag. I doubt it would a problem once acclimated to the time zone.
I wish we could have spent more time here. Would definitely stay again.
