We recently spent 4 nights at the Victorian Inn in Edgartown. It was one of the best B&B's we've been too. We chose the room with a large covered porch and it was a good choice (room 7). One day we had heavy rain, so we were able to enjoy our porch (the balconies on some of the other rooms couldn't have been used in the rain). The owners and staff were very helpful and nice. The location was great, we could walk everywhere in Edgartown.
The inn is pretty expensive (not unusual for Edgartown), but I was celebrating my birthday and wanted a special place. The rate includes a nice breakfast, afternoon lemonade, ice tea and cookies, flowers and sherry in the room, and use of beach towels and chairs.
There were a several repeat visitors during the time we stayed there.
