Inna's husband was there to meet us when we arrived and explained how things work in the apartment.
The apartment was cozy (no room for open luggage), but had ample drawer/closet space for us to unpack.
Location was good for those who are able to walk easily - metro and busses close by.
Inna was even kind enough to attempt to rendezvous me afterwards to try to return my Kindle which I'd forgotten in the room.
