If it werent for the hotel trying to make me change room during my visit I would note have too much to complain about.(One room was specified in the Airbnb agreement)
After speaking with two seperate receptionist the last one promised me to talk with his manager and in about 1h itnwas resolved.
Other than this i enjoyed the stay. the fee for the garage was a bit heafty, 15€/day but since it was locked and conviniet it was worth not looking for compedators.
Other than the price being a bit on the high side i still would recomend this if you are looking to visit Berlin.
Everything worked as advertiserd in the room i got. (1 person)
