Manuel was very nice and accommodating. He was always there to help when we had a question and he always responded to messages promptly. Son Serra was great for us, as two families with two toddlers - it's nice and quiet and the island isn't that big, so you can get anywhere within an hour or less by car.
The house is well equipped and stocked, the only things missing I'd say would be a kettle for tea (I think another guest mentioned this in the reviews, it's a British thing :) ) and an extra portable radiator for the winter months, when the house gets a bit cold at night. Other than that, you're just 5 min walk away from the beach, there are a few restaurants in the area and a local supermarket and for more options you only need to drive about 15 min to Can Picafort.
We really enjoyed our long weekend in Mallorca staying at Manuel's and would definitely recommend it!
