First trip to Mallorca and could not be happier. I cannot speak to the rest of the island but Soller and the surrounding towns are quite nice. You'll likely be in the Port often which is an easy drive, bike, or slow train.
As for the house, it is a quick 1 minute walk to the town center, shopping, restaurants, and helado! The house was fully equipped and had many places to hang out and enjoy the views.
Recommendations: Bike rental - Tramuntana Tours, Gelato - Giovani (so good), Restaurants - So many...try any/all. Miquel will give you better suggestions than I can...except for the bike and gelato, those are the best.
