We were here for two weeks in august (14.08.2013 - 28.08.2013).
The apartment was really great. We could find there everything we needed (toaster, teapot, iron, hairdryer and etc.). There even was sun umbrella =). Air conditioner was wery usefull in august. It's located near by historical center of Lisbon. Also it's about 7-10 minutes far from train stations (to Cascais and to Sintra) and port (to costa de Caparica). So you can chose the cost you want (We preferred Costa de Caparica). Tiago is the greatest host we ever met!!! We could easily call him or write with any question at any time and he helped us immediately. There was only one minus - it was rather noisy at fridays nights because of bars.
