Manuel and Teresa's place is in a good location, very close to the train station for easy travel to Lisbon or Cascais. Manuel provided great information on travel to the apartment and how to get around the area. I was met at the station to help with my bags and shown around to get my bearings. I arrived very early and I was allowed to leave my bag until check in later on. Manuel and Teresa were very helpful but they didn't intrude on my stay at all. The apartment was spotless and very nicely furnished with everything that you would need.
Estoril is a beautiful bit of coastline that's also close to Lisbon. The train journey along the coast is easy and pleasant with a view of the ocean. There's a bus to Sintra direct from Estoril and a bus to Cabo da Roca from Cascais which is 3 stops on the train. I would definitely recommend Manuel's place.
