The apartment was in walking distance to Sintra's train station and several nice restaurants and pastelaria's. Free parking next to the house. The kitchen was well equiped with all kinds of appliances and dishes, cutlery, etc. A cot and a high chair was provided for our 2 year old, which was great. It was a bit chilly inside (16 degrees), the weather was not so good unfortunately (bit of rain, 18 degrees outside). There were heaters and lots of blankets provided though, but I wouldn't recommend it in winter time.
We didn't see Joana, but she provided us with several good tips and was easy to contact in case of questions.
