just got back from staying in the bay, there is a boat for 1.70euro that takes you to san antonio they run every 30mins up till midnight, depending on where abouts your hotel is in the bay it isnt to much of a walk, it took us 30mins depending on how much had to drink amongst other things, haha it took about 5mins to walk back from eden. but anyway, even if u dont want to take the boat or a taxi its quite a nice walk.
