Never met Jaroslav but he was very quick answering to all the messages. He also was sure to ask us if everything was fine and if we needed any help with anything or if we needed any tips for our trip. The apartment is in a really good spot and nice and quiet. Except when it rained during the night the main bedroom with low sealing and skylight window were quite loud. :) I still would highly recommend Jaroslav's place. And it will be even nicer when the elevator is finished.
