Hi Kim, I will give you a complete response via the booking email which we received from you. It will be more private for you that way. But yes, there is no deposit needed. Your bookings are made directly with the landlords. Things in Cuba are informal. The landlords keep a written notebook with their bookings. For your booking, the landlord has simply written you in for your dates in Jan 2019.
Cuba is a cash economy, so your payments are made in cash, directly to the landlord.
It happens in less than 5% of cases that landlords will switch bookings and mess things up. This is an unavoidable things that sometimes happens. Usually it is made by mistake, but sometimes landlords do it in order to make more money or because they have a problem with their house (a flood or construction work, etc). But even if this happens, we would always contact you and work with you to find a new option.
In this particular case, with the landlord that you are booked with, I am close friends with him and he has one of our most popular casas. He is dependable and I don’t think you will have any issues.
I will write you more to your personal email
take care,
Mario
