Olga is a great host. She is punctual, accessible and flexible. She would help you with all your questions and address all your concerns (if any) immediately. Olga is considerate to her guests - she is treating them really well and makes sure they are happy during their stay at her place (e.g. during my stay she made a cake for all her guests). She is also just a great person to talk to. Definitely staying at her place next time.
