The House of Maps is pretty special. From the moment you walk up to the door and see the river you know the view is spectacular. Pedro allowed us to drop our bags off early si we could go and explore the city. He is full of little gems of information if you need it. The apartment has three good sized bedrooms all with views the beds are comfortable and spotlessly clean. Huge fans if it is too hot too. Wifi is good too. The station Cais d Sombre Station and Metro is opposite which can take you along the coast to Cascais. Good tip get off in Estoril and walk along the promenade into Cascais its 40 mins.
We ate in the TimeOut Food Hall right next door to the apartment over 30 different food stalls its amazing. Also a good place to get fruit fresh fish etc. There is a supermarket at the station too. Pedro recommended Casa De India to eat its superb locally caught fish and where the locals it. You can get metro passes which you can use on the trams too. I am a local to Lisbon so could throw out many recommendations but we went to Sintra. We brought on line a ticket for The Pena Palace and Gardens. You can get the train direct from Rossio station 7 euros return. The Palace is stunning. The 434 bus takes you from the station. You can walk back through the gardens back into the main square and National Palace. If you have time there is allot to see and allot is free check out. https://www.freetour.com/sintra tip based tour.
Walking along the river in Lisboa is a must as is eating pastel de nata.
You do not need to buy tickets for the castle the view is enough. Hope this is all useful and you cannot meet a nicer host than Pedro. Give him a hug from us... We will stay again. Jane and Liz
