Be careful. They cancel the reservation without warning. You risk staying on the street.
We booked with them in advance, no one asked for an advance payment. We called, agreed to contact in the morning on the day of arrival. We arrive in Minsk, but they don't answer the phone. I called back from a local number, they picked up the phone and said that your apartment has already been rented, we can't help you with anything.
They behaved very dishonestly in the context of the coronavirus pandemic. They refused to return the prepayment (reservation May 1-3, 2020), after negotiations through booking.com they offered to postpone the dates until 12/29/2020 (while Italy, for example, offers vouchers for 1.5 - 2 years!!!). The booking's request for confirmation of prepayment was not even answered. Thank you for the guarantees from booking.com They returned the money themselves. I do not recommend contacting you.
