What a lovely place. Stunning views down in to the Port. Massive sun terrace with sun all day and loads of furniture and parasols; the pictures don't do it justice. Huge lounge/kitchen/diner with comfortable sofa. Wifi was a real boon as was Netflix. Fully equipped kitchen meant we didn't have to eat out (and there are more restaurants down at the port and along the beach front than you can shake a stick at) and there are loads of supermarkets 10 minutes walk back down the hill (take a car or use a taxi when stocking up with the big 6 litre bottles of water). Comfortable sleeping and nice bathroom with a very welcome shower. Air con was a real help although we only ever ran the one in the lounge and not the one in the bedroom as that one kept the place cool. The swimming pool has been recently refurbished and the water is warm, huge sun terrace if you want to get a tan else about 15m to have a nice swim in and shower and loo. We can't find anything to fault it and would go back.
Port Soller is full of families with well behaved kids, young adults who don't get drunk and older people. No police presence, trouble-makers or litter, just shops, ice cream, restaurants and bars, beach, sea to paddle and swim in and boats to look at or hire or charter. Prices were largely comparable to the UK for most things, if not occasionally a little cheaper.
Be mindful that you should take mosquito spray, hydrocortisone cream and probably anti-histamine tablets as well as there are plenty of biting bugs about throughout the warm weather wherever you go.
