Start off with the good :) The hosts are fantastic and extremely communicative. They responded right away and when we had to leave early, they graciously refunded the remaining (pursuant to their cancellation policy). The place is also well located and is a good location for max two people for two/three days.
The three things I will note is that the apartment is much darker than the photos make it out to be. Even with all the lights turned on and the curtains open there is little light in the apartment. And, second, there is only one set of keys which makes things difficult if two people are staying there.
A very nice stay with very nice hosts!
