Me and my partner had a 3-night stay in this place.
It is not too pricy and located very conveniently. Electric heater worked fine, so we had not had troubles staying warm. But in the end I think we might have been better off paying slightly more and getting another place.
Everything in this "apartment" is extremely tiny, there's not much space for two people to move around, and seemingly double bed is narrower than it looks on photo. We had some troubles fitting comfortably at least.
Bathroom is a built-in appendix to the main room, fitting into a shower and rotating might be a challenge for a man. The door between a shower and a room exists mostly for the visual purposes, and did not lock properly. We did not really use the kitchen, but it does seem to have mostly everything to cook some food.
Window is facing the street, not a backyard as it seemed, does not really isolate sound and does not have any light blocking curtains whatsoever.
But that altogether can be lived with, the main problem is NOISE. Apartment is on the ground floor, first to the entrance and walls are extremely thin. You can hear absolutely everyone entering and exiting the building, house seems to have quite a lot of other rented spaces, so there will be quite a lot of it. Cars and scooters driving by can also be very well heard, and while it's not super busy street in terms of traffic, it adds up. I suppose in summer it will be even worse.
So as a solo traveller and with all noise/light-blocking equipment I think it's ok, but for couples planning to spend several nights do not fall for pretty pics and skip this place.
