The lemon house is lovely, clean and centrally located: very, very close to estoril train station and the beach. Simone arranged a taxi for us from the airport which was 35 euro and very handy. The taxi driver knows her and he let us into the house and gave us the keys, as we arrived late. She was available to answer any queries if needed.
The house is a 20 minute walk along the prom from cascais which has lots of nice restaurants beaches and shops. It's about 30 minutes from the vibrant city of lisbon again by train. It's very easy and cheap to get around on the train or bus once you get a viva viagem travel card for 50 cents ( it's a bargain!) . Then you can just top us the card and off you go.
Estoril itself has a lovely beach and natural sea pool. There is a good organic supermarket about 5 mins walk from house and a great pastry shop for coffee and croissant or other delectable delights. Simone provides a little map with these places.
Places to visit: lisbon obviously, sintra for palaces, guincho beach for wild, wind swept atlantic ocean. You can cycle there but we found it tough enough because it can be very windy. It's about 10 km by the sea on a cycle path.
Good restaurants- tapas do monte, your honest kitchen in the cascais market
