We had an apartment there for 25 years, and had to sell it when we retired, it is lovely. If you like discos etc. then it is not for you, but if you like to have a quiet drink or meal by a harbour it is perfect. You can walk along the front to Cala Millor ( all on the level) which has more restaurants and bars.
Visits should include - Caves of Drach, Caves of Arta, Palma, Soller and Valldemosa. Take the bus to Manacor and take the train to Palma - a beautiful journey and much cheaper than going by train here.
Don't worry - you will love it!
