Apartment is great but check-in was rough and not very flexible, host needs exact arrival time. I booked a 2-night stay and ended up arriving later than expected on the date of check-in because of a tour that went longer than expected in the previous city I was in. The host has another person come to drop off the keys but that person couldn't stay past a certain time. The host gave the address to pick up the keys from this person but it was far away from the city center and very inconvenient/expensive to get to. Also this person was going to be asleep by the time I got there. With no resolution to the dilemma, the host suggested I contact Airbnb to sort out the situation as if Airbnb could somehow give me access to the apartment.
So on the first night I had no way to get the keys and had to scramble and book another hotel while I was at the train station waiting to board the train to Vienna, it was a mess. I was able to finally get access to the apartment the on next day and the remaining 1 night of the stay was good. The apartment is clean and in a great location close to many attractions.
