Overall OK.
a) Be aware of the safety of the area before booking. Getting to the nearest metro is not that great at night.
b) White curtains with no lining and rails that only go to the alcove edge is a real problem unless you are the sort of person who isn't woken by blinding light at 5am
c) Minor issue with absence of bedding on first night, but clearly just a one-off oversight. The main bed is very comfortable, the sofa bed less so (quite hard with big ridges).
d) The place was clean and the hosts were helpful.
e) I don't much like that hosts induce guests to write good reviews via discounts. That does not make for good information and is likely to lead to misleading reviews.
Overall reasonable, perhaps pricey for the area, ok base to stay.
