Really a great value - even though the bathrooms are shared, I never had to wait to use one and there was never a line. Everything was very clean and the location is within walking distance of multiple museums and parks - and very close to the National theatret train stop.
The shared kitchen is also a big plus - plenty of room to store food and there are cabinets for each room if you're worried about keeping your stuff separate.
The only downside is that you are sharing a space with strangers, so you might end up next door to some loud folks. Overall though, I would definitely stay there again!
