It is a lovely place near the center (5-10 min walking) and next to the underground (2 min walking) to get almost in all the interesting places in the city.
It is full equiped and very warm.
Also, there's a supermarket and a bakery 2 min far from the apartment which is very useful. I would 100% recommend this place for anyone.
Christian replied very fast whenever we had a doubt, thank you very much!
