The flat was really nice and clean in a good location, 2 min from the metro, but host agreed to meet for check-in and didn't turn up. When I contacted the host they didn't apologize for not being there when they had agreed to be and were flippant the entire conversation from that point. They told me they wouldn't come and told me to open a lock box with a code to find a key and I had to struggle with a very difficult old door to get inside.
Nice place, shame about the extremely poor quality host.
