I originally booked this apartment on Airbnb but Olena changed to another equivalent one the day before, so the review won't apply to this one.
But the apartment we switched to was roughly the same on a slightly better location. We were 7 people and we had space for all of us. The apartment was clean and in great conditions, the check-in system was self check-in which was perfect for us since we were arriving quite late and we had all the towels and bed linen we needed.
Olena is very responsive and I had no problems at all.
