The flat is based about 2 minutes walk from the metro station but honestly you don't need it. In 5-10 minutes you can be downtown and start seeing all the historic sites. The flat is basic but comfortable for a short stay of 2/3 days. Silvia was great with keeping in touch and left us a map with detailed suggestions on which places were worth a visit and how to get there + some personal suggestions of restaurants and places to eat. There is a place close by recommended by Silvia called Sai Cao which you have to visit - cheap and home cooked Portuguese food! We didn't get to meet Silvia in person but her friend Nuno was very nice and welding and Silvia was always available by message! Just beware the bed is very noisy and the flat has basic amenities, but if you want a place to rest your head it's a good value flat. There's a cafe next door that makes coffee and breakfast for very good prices too and a supermarket just outside the flat.
