We had a very pleasant stay. The apartment was clean and the view from the balcony is phenomenal.
Especially striking was Olena's helpfulness prior and during the stay, providing detailed descriptions and videos about how to find the location of the apartment, the keys for self-checkin, how to operate the entrance to the parking spot and the (nonobvious) operation of the elevator.
Questions were answered quickly and in detail.
The pool downstairs was out of use, however Olena provided some drinks and sweets as compensation.
