We spend 3 lovely days in Manel's flat. The apartment was recently renovated and includes everything you need (towels, wifi, tv, big fridge) for a great stay. Also, there is a terrace where you can relax on sunny days...and there are plenty on this island ;)
Unfortunately, we didn't have the pleasure to meet Manel personally, though he was always incredibly friendly and eager to help. At our arrival we met his sister-in-law, who gave us the keys and showed us around.
Overall, we'd definitely recommend you to stay at Manel's apartment if you visit Artá!
