Couldn’t fault the hotel. Check in was nice and simple, quick too! Do note, you have to pay City tax at reception, however that’s standard across all hotels in Berlin. Bar downstairs was always lively at night, and the drink coupons for skipping room cleaning are probably a good reason to use it if staying for more than one night. Room was a great size, bathroom spotlessly clean, radiators and AC cool/heat was a great bonus as when I visited it was -6 and snowy, so definitely thawed me back out. Beds really comfortable. I booked a double room, however it was 2 singles pushed together, which was fine, but I believe it’s a standard thing in Germany,
Definitely recommend staying here, it’s good value, warm, clean and comfortable
