We stayed only one night. Great flat, cosy and charming decoration. Location is in the Belem quarter (near the famous tower and delicious Pastel). Around 10mn by bus/tram to the old center (don't do it by walk.. ~1h). All accomation is available in the flat (wifi, tv, hifi, equipped kitchen, table for 6 at least). Sofia and her friend are super nice. She'll welcome you with some Pastel, Ham and other stuff, and take time to explain you what to do and how to do it. If you don't know the city, just listen to her, she's very pationate and aware of the things to do. I recommend the place.
