Lets start with the positive. The Hosts are very nice. The flat is in a great location. The flat cute and clean, very small for four people. Hosts did drop of clean towels and bathroom garbage bags. The Negative was the stress of the toilet plumming issues nonstop and having to bag up our wipings (not being able to flush them) was not nice & inconvenient with 4 girls. The day after we arrived the overflow from inside the closet in the bathroom getting my sisters clothes wet was so gross for her and frustrating for her and my niece. The flat smelled like pee most of the time. I know about dealing with old buildings, its why we didnt leave the first night because we thought it would get better ( it didnt) I was trying hard to show my sister, niece, best friend a good time this was was a huge deal that tainted the adventure, from the first day waiting till 8:00pm before we could use the bathroom. Having to use local business restrooms when they were not happy about that was so uncomfortable & awkward. You both were kind and were genuinely trying to fix this but when you said it happens frequently our hearts dropped if this is the case it truly should be mentioned in your description..... Best of luck to you both
