We stayed for for 3 nights and had a great visit to Sintra. As mentioned in other reviews it is a bit out of the city and the walk home is uphill but that is Sintra. We used Ubers and they were great 4-5 euros to go anywhere and very responsive, cheaper for the 2 of us than the bus. We enjoyed being out the city after 5 days in Lisbon so the location was great for that. Great little restaurant near by about 7 minute walk, Nau Palatina, great food and you can’t beat the host, a must visit.
