The apartment at Chimburkova is very cozy, clean and well-curated. Everything was prepared for our arrival and Emil and Olga are very nice and always available. The communication with them via email was always fast and helpful. They also gave us lots of tips and suggestions of places in the nearby as well as a couple of maps of the city.
The position is quite good. If you do not feel like walking to the city centre (15-20 mins) you can get there by tram (5 and 9) or bus.
I would definetely recommend it and/or come back there.
