Downside:
The room is veeeery small :) literally only to step into the bed and out of the bed :)
Plus in the kitchen there is not table, nor much light - ie not good atmosphere for cooking, no possibility to sit down with your meal.
Upside:
Really good location & comfortable bad with lot's of light (if wanted).
All in all, for a shorter stay with not much time spent inside it is a nice option :)
