Pedro's place is in the historic district, on a secluded street inaccessible to cars. The apartment is a smallish one bedroom that is utterly immaculate and extremely well furnished. The location is perfect for walking to the commercial district, which is a little less than mile away, and to getting to the train station, which is about a half mile. The streets are safe at night, and there are plenty of little restaurants to try out nearby, but all the best upscale stuff (if that's your thing) is in the Commercial District. I'd advise you to take Pedro's offer to pick you up from the airport so he can show you how to get to the house the first time—he also suggested some great restaurants while we had him in the car, so that's a great resource to have on your first day in Lisbon.
