The flat is managed by a company, so, to be honest, I am not sure if I ever interacted with a person called Esther. Nonetheless the people I interacted with by e-mails, WhatsApp, telephone and during the check-in were all very friendly and efficient. They answer fast and were also reachable when I tried to contact them. We checked in on Christmas Eve and I was a little concerned that something might go wrong, but that was not the case. We called 30 minutes before arrival and there was a person there to receive us.
