The host and booking.com let us down.
Pros: We couldn’t get in. Cons: We couldn’t get in. We tried to contact the host on the day’s leading up to the booking with no reply. On the day we tried again multiple times but no response. We received access information but it didn’t work. The people that run the block eventually told us that the host was no longer in operation and the previous booking had had the same issue. We spent a lot of time and money contacting booking.com and eventually had to rebook different accommodation ourselves. It cost us a full day of our holiday.
