This was the ideal location - right in the heart of Sintra's historical centre, which is very pretty. The National Palace is around the corner, as well as many restaurants and little shops.
We were welcomed on our arrival and shown around the apartment which is the upstairs of Francis and Izumi's house, but completely separate from it. We had our own entrance to the apartment. The place was very clean and in a quiet location. There was food there for us when we arrived - a bowl of fruit, milk, coffee, wine, juices, yoghurts - all very much appreciated. We had a key for the garden - we never actually used this but it was very pretty and had a nice view.
Towels and shower gels were also provided. The kitchenette was very handy. The bed was very comfortable.
The place is well connected by public transport: The main train station is 10 - 15 minutes walk away - this connects you to Lisbon in 40 minutes and trains go often throughout the day. Some bus services stop right around the corner from the apartment, and others go either from the train station or from the train stop just before Sintra. The buses connect you to the beaches, and all of the palaces, which are the great tourist attractions of Sintra. As we were here in August, it was bustling with tourists, so getting buses early for a day out would be recommended.
There is a grocery shop located at the train stop just before Sintra and a bus service goes from there to right around the corner from the apartment which was very useful. Public transport is reasonably priced.
Francis and Izumi were friendly and we felt we could ask them any questions we may have had.
