Agostinah takes airbnb to a higher level, more like a guest house/small hotel. In the hall were tables loaded with maps/guides, pencils/post it notes, telephone/emergency numbers. Also hair dryer & portable TV. Don't cook on holiday but could see kitchen was well equipped, tidy & clean. Bedroom was fine. 2 min walk to bars/mini market, 5 min to town square & bus. Metro to apartment 11 min, & that's uphill!. Used the metro (cheap), but walked into city centre easily. Neighborhood a bit noisy at night with folk talking outside & dustbin men collecting around midnight, 6 nights a week (wow, what good service).
Lisbon is an exciting, vibrant city, be aware however that many parts are extremely hilly, but the aircon metro is never far away. As in any large city, including my own, London, there are beggars about, but after a firm "no", they desist.
I'd really recommend Lisbon, and look no further than Agostinha's. Si.
