Sofia and Mario's place is excellent. It's wide and spacious, and very well located. Everything was as it appeared in the fotos. Communication with Sofia was very helpfull and informative, and a fresh flower welcomed us on the dining table upon arriving. The train stations are less then 10 minutes walk away, there's a supermarket 3 minutes walk from the flat, and Sintra's main attractions and historic center are 15-20 minutes away by foot. We had a great time and would certainly recommend it.
