Nico is very kind and helpful. He is very trustable. The room itself and the common areas (kitchen and bathroom) are very clean.
Location is quiet and is very close to metro line. It's only 3-4 staitions away from City center ( about 10 minutes).
You can reach this place with metro from airport. It will take about an hour.
It's in the 4th floor and no elevator. So consider this if that's a problem. For me it was not a problem at all.
I will definitely recommend this place.
