Great location for either exploring Leiden itself (at north end of the city) or using it as a home base for other journeys (train station & bus connections a very short walk); there are also some nearby food stores & a drug store/chemists for shopping needs; not a super-picturesque setting but very practical and with enough people about (and security features at the hotel) to feel safe. And, given the proximity to the train & busses, it's remarkably quiet. I've also found the staff to be very friendly & accommodating.
Based on a prior stay I opted (solo traveler) for a room with a double bed and that included breakfast (varied & plentiful options); that gave me a bit more space in the room, while still being reasonably cost-effective. Efficient use of space, with some closet & open shelving, as well as a desk-like area and the all-important (for some of us anyway) kettle for boiling water for tea or coffee. Some signs of wear relative to a visit several years ago, but all was clean, comfortable, and functional - I can live with a scratch on the woodwork here & there.
Only small disappointment was that some UK-associated TV stations present when one scrolled through the options, and that worked in a late July visit, were non-functional come August.
