My wife and I had a fine experience in Lisbon staying in Pedro's place. Pedro was very helpful, and the flat very comfortable, with everything we needed there. The location was excellent, and mostly we walked to see central Lisbon, though there was also a metro close by and tram stop pretty much outside the front door. We were warned (after a minor incident) about walking alone down some of the narrow streets nearby, but felt totally safe for the rest of our time there. Everyone very friendly. The Nepalese restaurant opposite served excellent vegetarian food and there's a terrific coffee place nearby in Graca which we only discovered on the last day (yellow awning outside, in the main street).
