We thoroughly enjoyed our stay at Gabriel's cottage. The views are stunning and our favourite part of the day was watching the sun come up over the mountains from the terrace over breakfast. The property itself is very well equipped and has WiFi. There are lots of great walks from the door or nearby.
The GR221 goes past the gate. One of our favourites was the walk up the Gorge de Ca'n Cati, through Biniaraix (and a stop at the lovely restaurant there), doing the alternative loop on the return. The walk around Soller - Biniaraix - Fornalutz was also lovely. Great to have all this on the doorstep, but the property is also well placed to visit Palma on the old train from Soller, Port de Soller on the old tram, and the north of the island by car. There are bike hire shops locally in Soller too if you prefer.
As others have said, the drive up to the cottage is tight, as are many of the local roads - we started with a Seat Ibiza but changed it for a Fiat 500 on day 2, which is a perfect size for both accessing the property and getting round the many hairpin bends through the mountains if you're not used to them!
