Believe the hype -- for a very low price you can have a clean, comfortable and modern room in a lovely hotel with great staff, free wi-fi, and breakfast. The rooms are really great, with comfortable beds and flat screen tv. Staff was always helpful and friendly. Breakfast is your European standard cheese and meat and muesli affair, no complaints.
Motel One has eliminated a few frills that you will probably not miss -- there are no in-room phones, for example. So if you want to reach another guest, you need to leave a message at reception or get their mobile number. No big deal.
The only tiny fly in the ointment is that you are not exactly in the center of the action at this location. You're only a few minutes walk from an S-Bahn station, but if you are planning some late nights enjoying Berlin's legendary nightlife, you will be shelling out for taxis to take you back to the hotel.
If you're not much for nightlife then you will find it hard to find better value for money than Motel One Bellevue in Berlin. And even if you are a partier, a few taxis is not so bad -- from this hotel to Kreuzberg is about 15 EUR.More
