The apartment had everything we needed, including bikes with locks. The island of Caye Caulker is small, however the apartments are on the opposite side from the hostels and tourist areas, in a residential area. It was not a long bike ride, but is something to consider if people are wanting to be more "in the mix".
We paid for 3 nights, but had a change of itinerary on the second day, and decided to leave the next morning. I emailed Hilda that afternoon to inform her and to see if she could arrange a ride to to dock the following morning (as it would be a very long walk, especially at 6am). Then I emailed her again a few hours later when I hadn't heard from her. When I didn't get a response that night, we arranged a taxi to pick us up for the following morning. When I had wifi later that day, I emailed her again, to let her know where I'd left the keys out front, and still received no response.
