Flat in a great location (close to metro stop IP Pavlova), clean and nicely decorated.
For some travelers it might be worth mentioning non-issues for me, but might be for you:
It's in the 3rd floor and there is no elevator.
With host we just exchanged keys and didn't chat much, so I didn't know whether they provide local insider touristic info (there are some brochures in the flat though).
There were some minor issues with flat amenities (loose screw on a door handle and loose faucet). Hope they fix it soon.
Overall, I can recommend staying at Birchwood.
