We chose this historic inn based on central location to everything we wanted in less than 15 min. Front desk staff (Dwight and others) are fantastic and always willing to listen and provide assistance. Fort Zachary Taylor Beach Park is walkable - 25 min (beach water shoes recommended due to rocks). We didn't need to rent any transportation as it was easier for us to walk it out, so I can't comment on parking since I didn't use it (it is limited at most places). We felt very safe walking around, even at night. We used a taxi to and from Key West airport (both drivers familiar with this inn). Room is clean. Both night stands have power and USB charging outlets. Excellent daily room service and Sunshine Breakfast basket hand delivered to your room. Duval Loop bus stop 14 (free) in front of inn (bus route loop is an hour long and two buses running to ensure next bus in 30 min), so this is another convenient option if walking isn't your thing.
