Not suitable for more than 2-3days. Very loud, if you want to sleep this is not the place, windows are not isolated or less. Missing important things for a long stay, stuffs to cook (yes there are plates and cutlery to eat), nor a table to eat, you have to eat standing in the kitchen or in the sofa with your plate. Not suitable for work as there is only a small coffee table which is low so you can't use it for more than some minutes with the computer (or eat).
The disgusting part was the smell in the bedroom, it took me 2,5 days to figure out the strong rotten smell was coming out of the mattress, they changed it, but the smell stayed in the spring box which hold the mattress (for sure for long to stay impregnated like that). When entering the room you can already smell it in case they don't change it. The wall also smells funny.It was very unpleasant to find out I was sleeping in rotten mattress. Definitely not what you expect when paying 1000euros for 13days.
Bathroom also need some renovation, shower door doesn't close so you get water in the floor every time. There is rotten wood in between the shower and door at the floor level which show crawling bugs every day.
I think price its too high for what you get.
I didn't meet the host, but he answered fast and solved the issues I reported, but never checked if the smell was gone for example, after the mattress change. I was not offered another option either, and being tired to move again I just stayed, but these things shouldn't happen, guest shouldn't have to discover rotten mattress and report it, instead the flat should be clean and ready to offer a good stay, not just react to solve issues.
