We had a great stay at the Otto Hotel! As other reviews mention, the rooms are rather small, yet, very beautiful, modern and comfortable. The beds and bathroom ware impeccably clean & cleaned daily! Other items in the room could have been cleaner - closet space, phone, bedside table were a bit dusty. The staff is reserved, yet, friendly and helpful. In regards to location, the hotel couldn't be better - it's quite central and right across a metro station. It's easy to find the hotel, as they now have clear signs outside as well as friendly staff awaiting you downstairs. Please note, this hotel does not provide breakfast and doesn't have a bar where you can have a drink or some food, which was fine with us! We'd stay again.
