We had some major issues with our flight so we were actually a day and a half late. I emailed Andie letting him know that we wouldn't be checking in day one and he promptly responded. He did mention that the keys would be "under the mat" which I didn't think much about. Unfortunately we ended up arriving past midnight to the unit very tired and cold and it turns out we needed to get buzzed in to get to the mat he was referring to. After an hour we finally got let in by someone walking in. I'd advise to always leave the keys in the lockbox for future guest, but he was very apologetic the next day.
The place is exactly as advertised, clean and the pictures matched reality. There is a great bakery nearby and the street is very quiet. We did get someone (looked like a worker) walk in without knocking and he was so focused that he didn't see us until we yelled. I'd stay again, just keep Andie more informed and keep the door locked :)
