First of all, the location of the apartment is really cool. Everything is close and it's in the center with a nice view and (surprise) pretty calm at deep night. However you need to keep in mind, that the house is very old, so you'll have a specific smell from pipes, very small shower etc.
Michelle is really friendly and KB is fast to answer, but it seemed to me that both of them are unprepared for unexpected situations. I got two issues during my stay 1) almost no wi-fi for three days 2) issue with electricity - when you turn on the light in the bedroom, everything else goes down
With wi-fi I've needed to wait until the company fixes the line (no other options were suggested). With electricity I found the reason of the issue myself and just didn't touch the light in the bedroom until my check-out.
So to sum up, the apartment is pretty cool, but don't expect any real help in case of any emergencies except apologies)
