My boyfriend and I stayed at the flat for 4 nights. We really enjoyed our stay! The flat was very clean, had a large bathroom, good size shower and a very comfortable bed. Flat also has a washer and dryer which came in very handy.
This flat is located in an excellent location. We walked just about everywhere from here. There are many excellent restaurants and bars nearby, not too many tourists.
We had a minor issue in that there was a horrible rain storm that caused the roof in the kitchen to leak pretty bad which caused the kitchen floor to flood, I informed the host but not much he could have done. Luckily it only rained that one day!
As other posts mentioned, the flat is in a busy location and it can be very loud at night with people walking around outside. Walls also seem to be very thin as we heard EVERYTHING the girl upstairs was doing!
Overall though, I highly recommend this flat. I would definitely stay here again. Hosts were easy to communicate with, and check in check out process was extremely easy!
