Central hotel that tries to...

Liked: Central location close to S-Bahn, value for money ok
Disliked: Room was big but seemed sterile, very empty and without decorations. Facilities in poor maintenance: Sink was leaking, balcony door was somewhat broken. Staff seemed a bit clueless.

Very poor

Liked: Nice facilities
Disliked: The personal at breakfast was extremely slow and did not ask if we needed coffee or anything. This is very bad considering the breakfast was quite expensive

Exceptional

Liked: Wonderful hotel, with wonderful comfortable and quiet rooms, comfortable bed. Breakfast is not included in the price, but it is definitely worth having breakfast at the hotel. My family and I enjoyed staying at Boston hotel.
Disliked: The price of parking should be cheaper.

was okay but i will...

Liked: nice central location, pleasant sauna facilities and large room.
Disliked: the hotel does not have air conditioning, an in-room fan is provided but noisy and does not lower the temperature, so we slept with window open and had quite some street noise. The bar, lobby and breakfast area was really warm and not even summer yet.. After spending some 300 euro for 1 night plus parking and drinks i had to pay 3 euros for a check-out coffee-to-go - not good.
