We stayed in room 8, it is a cosy (i.e small) room but definitely great value for money! The kitchen was very well stocked and toilet very clean. The noise from the street is loud so if you’re a light sleeper I would recommend ear plugs - I think in normal circumstances Ryan would supply them but I’m guessing because of Covid this is no longer the case!
The flat is in a good location, about a 20 minute walk from the castle and old town. It’s really easy to get around. Would definitely recommend for a short stay in Edinburgh :)
