We just stayed 2 nights and only used the apartment at night but from our short experience we can tell with certainty that:
Elena is a kind person and responds quickly.
The place is at 5-10 minutes from the train station. 1 minute to a local mall, that had a gym/cafeteria/grocery store.
Quite place, and we felt safe when we came back to the apartment at 5/6am from the train station.
Clean dishes, bath towels and sheets, the place also had gel, hair dryer and we could even iron our clothes.
Warm place to stay at night, I could even sleep shirtless and we stayed mid November.
Would come back, highly recommend it.
