So I stayed at the numa for 3 days. Basically, the room is like a hotel room, but with a place to cook. The room was small but it had everything that I needed. The kitchen space was small so it was not super comfortable to cook there, but it's possible. The only thing that I did not like was the room temperature. It was quite cold, especially floors. So I recommend having some warm clothes with you and maybe slippers.
The good thing was a welcome gift at the mini bar also nice tea, coffee, and some cooking staff in the kitchen.
Also, the location was nice. The city center is close and a metro station was just across the street.
I think it's a nice stay for a few days if you are not going to spend a lot of time at home. I would stay there next time for sure.
