We really enjoyed our stay at the flat. It truly is a studio so both beds are actually in one room (living room area). One of the beds is a pull out couch, and it is reasonably comfortable. The place was immaculately clean. It is honestly the cleanest Air BnB I have ever stayed in, which was very much appreciated. The bathroom is nice but note that the water saver shower does not produce much water pressure which can be a bit tricky. The flat is well appointed and the host went above and beyond making sure we were comfortable. The area is indeed noisy so make sure to bring ear plugs. Some neighbors across the street obviously do not realize some would like to sleep at 3am, which was not pleasant (obviously not the host's fault).
Great location, both for transportation purposes and shopping needs.
