Spent a few nights at different times on "pier" hotels - first time i spent the night giving out about the noise the air conditioning was making - after kicking the crap out of it and eventually turning it off, my young lady friend pointed out that the noise was the sea splashing againts the shore underneath !! Comfy enough but not for sleeping !
try fulay gh.
Maybe a little bit commercial now, but it's still the best.
And very friendly staff !! Normally I stay some days before I get sea-sick and have to change to a hotel on fixed ground.
Some pictures are on my homepage.
Fulay is OK, but the comment about the noise from the waves is correct. If you are a light sleeper like me, suggest the GH on the other side of the street.
