The room they gave us:
Smelled like wet dog, and even if we left the window opened the whole day, it kept smelling like this till the last day.
The bathroom sink was not draining properly water so if you opened a bit more the water flow the whole sink was getting overflown.
The internet connection was just ridiculous, a 4 star hotel, where you have to pay to have a decent internet connection!?!?! In other hotels I have never experienced such a bad connection. The free bandwidth was up to 256kbps which is hilarious for today services, and it was limited to 100MB per day. Moreover it kept asking to register again each of my devices everytime I was using internet.... The upgrade costed 9.9€ per day!
Moreover the windows were not sound proof so even if from the road there wasn't much noise coming, all of it was getting into the room.
ps the hotel staff asked me to pay extra 50€ to have a room on the other side of the road, with a park sight. Clearly that was not a park but a disused hippodrome, where they also held some very noisy parties during our stay...
I will never go back to NM hotels, not even if they are free!!
The room was big and bright, the staff was helpful and nice enough.
