Katya is a great host, very welcoming, ready to answer any questions and providing directions for local places and events throughout the city. Room is small and simple, cozy and, in my opinion, fulfilling it's task as a place to stay for a tourists.
Subway really just 5 minustes by walk, plenty of nearby shops, providing everything you might need. Some coffee shops, bars and restaurants too. Neighbourhood is ok.
Spent almost two weeks there and definitely looking up to book there again!
Added bonus for any Russian-speeking tourists: Katya speeks Russian perfectly, so even if your English is limited, you will have no problems communicating with her.
