This is the perfect of place to stay for the location ( you cannot beat this location for the price) and to come back to just sleep. - which is what we used it for.
The stairs were not really an issue at all for us. But the apartment is small and I would say only suitable for 2 people at the absolute most. The linen was fine, I would say it was just dusty.
It is a really great location, we stayed for 4 nights and by the end of it, it was feeling quite cramped and the washing facilities are not very practical as clothes don’t dry very quickly.
I would also say that we got very frustrated with the shower, it’s very small and the doors don’t shut properly and water gets on the floor. So I would request more towels so you can dry the floor.
Also note that the fee for the tourist stay is not included so you need to have cash to pay this on arrival. We had not had this happen before as our other air bnb places adjust the price as soon as we book or include it in our stay.
