Emil was a very polite and kind host. It is apparent that he wants his guests to have a nice stay and offers various recommendations on attractions / restaurants in the area. It is also very well located and has easy access to the metro. We enjoyed our stay very much and even decided to stay in the last night and ordered take-out and bought a bottle of wine to share on the balcony to take in the nice view! I would very much recommend staying at Cloud Nr. 9 :)
