We stayed in one of the studio offerings - the Heron I believe - and my wife and I loved our stay. The main office is about 10 blocks away, but the walk was easy and straightforward. (We could have jumped into one of the numerous cabs, but we wanted to stretch our legs.) The neighborhood was busy in a safe and comforting way. The studio apartments are close to the street, so we had a bit of "street noise" in the morning, but it was not anything too bad. We loved the location as it was close to the water and offered access to Duval and other great points, but the location itself was not too loud.
Given the high cost of other places to stay at Key West around Christmas time, we were happy with the price. Overall, the accommodations were very fair given the price point. We loved the daily touch-up by housekeeping, and everything was clean. Some of the appliances were a touch worn, but again we were very pleased with these accommodations given the cost of renting in Key West.
We will definitely rent through this company again (though we were totally nervous beforehand, as their presence on TripAdvisor is so limited.)
