The Numa / Belfort is a lovely and charming old building. It has everything you would need for an in town stay. One caveat is the walls are very thin since it is a typical old Berlin building so normal conversation and music levels can be heard by neighbors. If you seek a very quiet holiday spot this place is recommended.
We ran into an issue which was handled beautifully by the guest services Manager over European properties. She was lovely and everything was settled to our satisfaction.
Thank you Numa team!
