Brilliant place to stay at, as a large group. Pretty good location, just ~10 mins away from Innerstadt. The loft is actually a part of Mercure Hotel, which I wasn't aware of. The receptionists at the hotel were extremely kind, despite the loft being managed on Airbnb. You can also choose to have paid breakfast at the hotel if you'd like.
PS. Panajotis is an amazing human being and all the pre-trip communication with him was flawless. Highly recommend if you are travelling in a 4/5 people group.
