Thanks for your inquiry about short-time flat rentals on Lamma.
There are NO websites about home rentals on Lamma, except this one. None of Lamma Island's property agents has a website listing available properties and just a few of them use email occasionally.
We have a free forum for renting and letting flats:

Here are some contacts of most hotels/guesthouses/holiday resorts and their agents:

Call them up to check availability and prices.
Then the best way is to simply come here and visit some property agents offering "holiday resorts" along Main Street and rent something on the spot.
