As always, my opinion it’s my proper experience.
To be fair, especially for host - I have to divid my rating into 2 parts :
1) Host - extremely nice, super well organized, very helpful ( You can be sure that it will be the easiest possible check-in in your life) : rating ? Absolutely 5 stars.
2) private room - localization? Perfect. Room - clean, well arranged, but extremely small. But the worst this is a room without window, in the middle of the kitchen without fresh air and it’s simple not acceptable. This is certainly not 5* room.
I have also a doubt of an official rating of this place because I can’t imagine it’s only me who doesn’t like super tiny, without natural light and fresh air rooms.
