We travelled by train to Berlin and at the time of arrival had been on the go since 4am. Check in for this Airbnb was stated at 3pm on his listing and two days prior, I messaged Christian to say that we'd arrive at 5pm- he responded to say that he would be working until 8:30pm and that he "had already told us this" (which he had not) and that we could pick up the keys from his store if we wanted to check in earlier. He then followed this with another message saying he would be home at 6:30pm and would meet us at the house then. We agreed to this and arrived at the house at this time, but when we arrived got another message saying that he wouldn't be there until 8:30pm. We were exhausted at this point, having travelled for 14 hours already so urged him to please meet us as we had previously agreed . Thankfully, we only had to wait 10 minutes outside before he did so, and he was apologetic.
Despite this confusion with communication at the beginning, the rest of the stay was great. The flat is clean and close to a tram line that is about 20 mins from Alexanderplatz. There are some local stores and nice restaurants also within walking distance. Christian was very friendly and gave us plenty of space and privacy to go about our business.
