Antonio's place was very neat and clean. There was a little table full of information about things to see and do in Sintra. Also, a very sweet lady let us in when we arrived and Antonio himself came to the house especially for us to explain things and to introduce himself. He is very nice and friendly. The house was very spacious and the City of Sintra is walkable. However, we needed to use Uber a couple of times. That was cheap so not a problem at all! You have an Uber ride for 4 to 5 euros and sometimes even cheaper.
