Cleaning (doors for example) must be more intensive and frequent.
In the shower the water did not drain , it must be cleaned from the hair.
Dirty walls to the common areas for example the stairs and also the garden.
Use of the kitchen only until 22.00.
The girl that I saw (the owner I suppose) and that left the keys for me to check in did not even spoke to me.
I felt unwelcome.
Succesful business needs also a contact with the customer/guest...
In addition, too many rooms/guests in a single house with small common areas. You could feel restricted.
Positive points: the location near the train station (Centrale) and the metro (Sondrio) & the quite area/road.
But (50€) I still think expensive for a common wc room.
