Ingrid was out of town so we never met her, but she is very responsive via text and email. She arranged for us to pick up the keys at a local coffee shop, and this was no problem. The apartment is in a fantastic location, just 2-3 blocks from the Eastern Parkway-Brooklyn Museum subway stop. There are restaurants, bars, grocery stores and a yoga studio nearby. It is in a classic old Brooklyn building. The apartment is lovely, very well equipped and full of books and art so you feel you are house sitting for a friend -- a very brainy and interesting friend! When it came time to leave, there was a problem with the keys. Ingrid asked us to leave them back at the coffee shop for a friend. She said if they were reluctant to hold the keys there, we might try leaving them at a different coffee shop several blocks away. This introduced an unwelcome element of anxiety for us, since we were on our way to the airport to catch a plane and didn't have a lot of extra time. As it turned out, when we left, I thought my husband had the keys and he thought I had them, so the keys ended up being locked in the apartment. We hope Ingrid had a Plan B for the keys.
