Our stay at Nicolai's place was fantastic!
The apartment is quite central and can be accessed easily via nearby metro. It has everything you need and Nicolai even provided additional blankets as it can get quite cold during winter and during the night, so be prepared for that.
Nicolai is very kind and easy-going and allowed us to check-in a bit earlier and also to leave our bags at his place a bit longer, which we appreciated very much as it really helped us out!
Overall we had an amazing stay and there was nothing to complain about. Thank you so much Nicolai :)
