Charlie was a great host. He replies very quickly and is very hospitable. Check-in and check-out were made easy with detailed instructions. The apartment is in a good location, close to bus and subway lines, and it has all the basics you would need. I will just emphasize as others have (and as Charlie himself notes) that the train is very close by and runs frequently. The tracks are about 6 feet away at about window level and trains run every few minutes during peak times. They stop for a while late at night to early morning, but ear plugs are definitely recommended. I'm a fairly heavy sleeper but still needed the earplugs. Also note there is no bed, but the pull-out couch is fairly comfortable if you like firm mattresses. Would recommend staying here for short visits and business trips.
