The apartment is a nice and cozy place, well located (close to tram and subway stations to go anywhere in the city and also close to nice restaurants and supermarkets) that has a great price and offers nice comfort.
During our stay during summer, we realized that because of the house boiler getting too hot we need to use the air conditioner all the time (and the air conditioner is kinda noisy), but nothing that would disturb your stay too much.
We loved the place and we would definitely come back.
