Kevin is really helpful host-he even picked us from train station and lead the way to the flat.
It is small but really comfortable place - windows are isolated and you don't hear noises from trains.
The only thing that is worth mentioning that there is limited hot water - it lasts for estimated 15 min I guess but for two people is it completely fine.
10th district isn't the best neighborhood but we didn't encounter any troubles on our way.
By the way elevator is really cool - check it out yourself :)
For this price it is highly recommended!
