I'll give you the good, the bad, and the ugly.
Good - the location is great. I was able to walk to all the tourist attractions as well as restuarants nearby on the street.
Bad - there were breadcrumbs on the counter top, the living room floor (wooden) had hairs and dust, the bathroom towels and bedding had stains (were clean though), there were towels left in the dryer
Ugly - the dryer is useless as it doesn't dry clothes on the first attempt. The noise within the unit was unbearable. I tolerated the footsteps as that's normal, but there were times were people were running around and screaming. Upon checkout the host asks for the dishes to be cleaned even though he's charging a cleaning fee.
Overall, I give the flat a 3/5.
