We stayed at Mark's place for 6 days and we enjoyed it. It felt like home. It has all the amenities you need and some other things we appreciated (e.g., coffee maker with coffee pots, shower gel and shampoo, beach stuff, smart TV). The house is small but very looked after and very clean. Location wise, it is 3min from the beach and 2min from the bus stop that takes you to Ciutadella (20min ride). It has a supermarket and a rent a car/scooter (which we used and all went good) just next door. The only negative point we experienced was that (sensitive to noise people) there isn't sound isolation between apartments.
Communication with Mark was very good, he is very attentive. All in all we recommend you to stay on Mark's place!
