We stayed 4 nights here. The ad does say it is small, but I would add super small. We don't think this place is big enough to fit 2 adults and their suitcases, given that you don't have room to open both suitcases at the same time. Fair to add there is an option to unpack and put luggage in the garage which is separated. I would estimate the place is no bigger than 16*2 smr.
Besides the size, the host is perhaps the nicest person in the Southern Hemisphere, and tried her best to make us comfortable. 1 min walk to the beach.
I would recommend to transform the very nice patio into another room in order to add some very needed space.
