I am sorry to leave this review because overall the people tried to help, and I am not used to leave negative reviews but:
1. I explicitly asked for a good WiFi before booking because I had to work from here. WiFi was almost not existing (they say it's the first time they have this problem, but as you can see from other reviews, it's not true).
2. It was not very clean. Some things were clean, like the bed. Some others I had to clean them by myself like very dusty drawers and balcony that has never been cleaned for years
3. Few things are broken. The roller shutter was fixed when I asked for it, but in the toilet there's also a leaking pipe.
In general, this apartment needs some proper fix before being rented for long stays, it might be suitable for short stays, but you could probably find better.
The people are, overall, responsive and they try to help, but the problem is at the base: if everything was working properly you wouldn't need to ask for help
