We stayed in Pedro's apartment for 8 days and it is definitely in the best area if Lisbon. It is quiet but central and not touristy. All of the restaurants, bars, cafes and ice cream shops around the square are fantastic and the square itself is beautiful to sit in. The apartment is clean, authentic Portuguese and the patio a lovely place to sip wine in the evening or drink coffee in the morning. The neighbour Isabel is very kind and friendly and Pedro's recommendations are worth listening to- we ate in Terra and The Vegan Project which he suggested and both were excellent meals. If we return to Lisbon we will be staying here again and I would recommend you do too!!
