We had a quick one night stay in Tomas's place. It was on the top floor (with quite a narrow staircase so be aware!) but had a lovely open plan layout. We were greeted by one of Tomas's colleagues who was very helpful and had lots of information. Bed is a futon but still comfy. Location is great, just walk up the street and you are on one of the main roads in the Alfama and walk down and you are on a square. Also highly recommend Taberna Sal Grosso for lunch or dinner round the corner, one of the best meals we had!
