The Sky Room is an amazing find. Really lovely, clean and convenient for staying out of the city. The bathroom is well equipped. There is a fridge and decent amenities for the kitchen although we didn't use them as we ate out every night. The flat is really close to a subway, less than 2 minutes walk.
Rain was really responsive and accommodating as well, just a great host!
The room is next to a road that isn't very busy in general but once or twice (as is expected in a city) in the night a siren could be heard. If you sleep with earplugs then it isn't an issue and the Aircon (if needed) can drown this out.
