I will start with the negatives, they were more than the positives:
1. There were no bed sheets and towels /unless you pay an extra 15 euros per person/
2. There was no kitchen kitchen sponge and we weren't able to clean the kitchen table.
3. Extremely noisy outside on the street, which can be expected for the center location, but window frames are old and can't isolate the noise.
4. Low ceiling /mind your head/
5. Difficult to get in and out of the building door /the last set of stairs before the door are very tricky/
6. No power sockets in the bedroom
7. No microwave
8. Very expensive
The positive things:
1. Central location
2. Spacious flat
3. Smart TVs
4. Convenient bathroom
Overall I wouldn't recommend this place, not worth the price, unpleasant expirience.
