Small room that is very inefficiently designed. E.g. long corridor that is too wide to walk but to narrow to comfortably put luggage. Bathroom door opens to the inside, easily collides with shower glass door or hits the knees of anyone sitting on the toilet. Better communicate clearly. Lighting concept: very bright or very dark, nothing in-between. Little space to put luggage but almost no drawers to put clothing. Luggage can also not be placed under the bed (boxspring design). Very little space to walk around the bed and multiple obstacles (e.g. a pillar), so better be careful at night so that you don't bump into anything. I wouldn't recommend switching on the light though, because, again it's either super bringt or pitch black. The lights at the bed are very bright ceiling spots that directly target the eyes of both people in the bed (no separate control for each side).
Neither the room nor the bathroom are too small in terms of total area but the design is just so bad that it feels very crammed. I haven't stayed in a hotel room this badly designed in a long long time. I have stayed in smaller rooms that were a far better experience.
However, it was clean, good location, and had a good view (lake view room).
