The host was great, very responsive and even let us check out late which was so helpful as we had a later flight home. The place was as advertised, clean, and had everything we needed for a comfortable stay.
Light sleepers beware - there was a neighbor playing very loud music from midnight until 9am and a light outside the courtyard we faced was on. Luckily I had a noise machine and an eye mask to help fall asleep. Would recommend to the host getting darker curtains / one in the kitchen to help.
Besides this which was out of the hosts control, the stay was great! Super easy to get to the airport / other parts of a Berlin from.
