We found Lisa's apartment with a taxi from Sintra easily. Her directions were very good and clear. The apartment was spotlessly clean and freshly and newly decorated and refurbished. It's views are almost 360 degrees! And truly fantastic. The feel of the apartment is fresh, airy with high ceilings and she has left the original features on the ceiling and floors etc so it still has a touch of a Portuguese feel. However it's very modern too and minimalistic in its furnishings. We had a lovely 3 nights there. The weather was glorious for this time of year, early April and we were just warm enough. There are a couple of heaters which we didn't need.
The surrounding area is residential, a very nice area. Walking distance from the train station, although hilly if you have luggage. Lovely area to explore on foot if you can walk up and down hills. And by car too. Lisa is very approachable responsive and friendly and told us lots about the area and shops etc. With a map. She also was helpful as we asked to leave our bags after check out which was no problem to her. Security was good in the house and the garden below which we could use too. Lisa is not on site which wasn't a problem and her family are nearby. A lovely host and apartment.
