We enjoyed our stay in Salt Loft - it really is as charming as the photos suggest. As others have noted, the second bedroom and upstairs shower are a squeeze for adults but the main bedroom, kitchen, sitting room and downstairs bathroom are big enough.
What let it down was the poor attention to detail, such as only 3 of the 6 lights in the downstairs bathroom were working, only 3 wine glasses (for 4 people!), only 6 clothes hangers in the wardrobe, no shower caddy in the downstairs shower (requiring a lot of bending over to relieve soggy soap etc), no decent rails in the bathrooms to hang bath towels to properly dry, the standard lamp in the sitting room could only be turned on at the plug (requiring more bending over), there were numerous reed diffusers but none had any oil in them, and several of the tourist brochures were well out of date. None of these things particularly detracted from our enjoyment of the cottage but they are not what I would expect to find in a property let by a business with the word "luxury" in its name and priced accordingly.
Note that there are internal windows at high level between the two bedrooms with no blinds, so if the light is on in one bedroom during the night it will light up the other bedroom, which may be an issue for light sleepers. As other reviewers have noted, the seagulls are very noisy so best pack earplugs!
