Ricardos apartment is a gem. I especially loved the minimalistic and clean design. No frills, no overdecoration and composed with beautiful, rough materials: open cork insulation, wooden/concrete floor. The kitchen is basic, but has all you need and everything works well. Sharp knifes, wahoo!
We spent most of the days exploring the area by foot. Hiking trails are very well signposted – look for the red/yellow or white/yellow signs. Basically you can spend a whole week just strolling around. The scenery is so beautiful that we almost forgot to visit the "actual" sights of the area (Sintra, beaches, Lisbon etc.).
