Its great value for money. The host being available after I expressed my concerns regarding the down payment

The requirement of a down huge payment that I had never experienced before. To be honest, I did not check the 'important information' section of the booking, so that is what I could do differently, but in all the years I used booking I never ever paid so much down payment. I am even pondering if I would ever do it again but that is a different question. Despite it being an (unnecessary) upgrade the host unexpectedly giving me a different apartment, without calling me directly, because he assumed I had a car which was not the case. This is not related to the host/apartment: Not sure if it is already there but I think booking.com can make an improvement in the list of rooms/apartments that are shown by also showing if a down payment is required (and how much).
