I went diving with Aqua Adventures in January this year. Sharon is awesome to work with and they are a very good operation. The boat captains and the guides are all great. I've attached a YouTube link to a short video of the night dive from the boat so you can see what the boat looks like. You can back roll in or step to the back and do a giant stride. The engine is in the center of the boat, and the aisle between the wall of the motor cabinet and bench is wide enough for one person at a time to walk.
Once you get off the ferry, you can hire a bicycle taxi to get you to Aqua Adventures and La Vida Dulce, and they work for tips. It was very helpful because of the cobblestone streets and uneven pavement, and dragging dive gear even for a few blocks would have been difficult.
Sharon can also put together a dive and stay package with La Vida Dulce, which is a B&B type place, and it's right next door to the shop. It's centrally located downtown with shops, restaurants, banks, and a grocery store. La Vida Dulce has a small kitchen with a microwave but no cooktop, at least the unit I was in. And it's air conditioned.
It's a short walk from the shop to the marina, about three blocks. Here's a few pictures from my trip. I spent 10 days of diving there, so if you have any questions, feel free to ask.
