Marina is great host and helpful. We were at Marina's place for 10 days and did not find any difficulties.
she was flexible with check-in and out timings.
The apartment was in the basement of the house and has its own entrance. The neighborhood was calm and quite.
The place is near to S station 2-3 mins of walking and you will be at train station.
A bit smaller shower and slower WiFi, other then that everything else was perfect.
I would definitely visit the place again if I get chance.
