My stay at Marlena place was great. She has a separate room for her guests thus one can have as much privacy as one needs. She provided me with fresh sheets and towels, was very forthcoming about my check-in (since my train had a huge delay) and let me use her washing machine.
The only downside might be the location of the apartment since it's located more outside of the city center. But that's absolutely manageable with public transport (subway).
I enjoyed my stay at Marlena place!
