Lovely and cozy little appartment in the San Pedro quarter of Sintra. Place was as nice in reality as seen on the photos, very clean and great communication via message with host Sofia. Some nice little extras such as olive oil, vinegar, salt, etc. in the kitchen so we could start making use of the kitchen right away without major grocery shopping beforehand.
Location a little further up in the mountain, not in the centre of sintra which was an advantage as this places major monuments (Pena Palace, Moorish castle) within walking distance (approx. 25 min, uphill, not suited for people with walking disabilities) and you don't get stuck in the traffic jam on the major tourist route between Sintra centre and the Pena Palace.
Little shops and a couple of restaurants nearby. Sofia provided a list with restaurant recommendations which was very helpful. Be aware that many smaller restaurants are closed on Sunday evening and Monday (as is customary in Portugal), but you will always find 1-2 options.
