Apartment is located very convenient for walking distance everywhere(railway/center).
Apartment is warm (using thermostat)
Be aware - nothing is in the apartment at all, no dishwashing tabs (even though there is a dishwasher), no sugar/salt, even no bed tables in the bedroom, just one garbage bag.
So if going with a family(kids) you'll need to buy all small stuff that could be needed if you stay more than 2-3 days.
No elevator and apartment is on the 3rd floor (5th if to count 2 firsts).
3,5 out of 5, I'd say, as it lacks a lot of stuff and could be more cosy.
