Extremely difficult to find and nearly impossible to navigate to apartment. Directions are provided via a handheld iPhone video post-booking that assumes you know where the video starts from and requires tight, technical driving skills down narrow one-way, stone-lined mountain paths. I was stuck in my tiny Ford Fiesta getting in (1+ hours to find the place even once already in Soller and stuck getting out, 1:45 hours to leave that also required backing-up down narrow mountain pathways lined by very tight stone walls (mirrors pulled-in, etc...). Very difficult and not clearly advertised before booking.
There is street parking if you can find it about 15-20 minutes walk away. The parking images provided by host are for the neighbours who live there full-time (who also are up at 6:45am working loudly). I parked on the narrow path by luck just down from the house the one night I was there, but it was very challenging and taxing.
The place itself is a one bedroom and is nicely decorated, but is dark and damp feeling. There were cleaning supplies left out on arrival and the neighbour/gardener/repairman came the first and only night I was there to fix things until 8pm.
The host is kind and communicative, but I am sorry I can't recommend this place. I cancelled the booking after the first night and booked another place due to it's inaccessibility and wet feel.
