We had a great stay at Sandra's. The location was perfect and the apartment was very clean and safe. It is 10mins walk to the main street of Baixa Chiado, and is near to popular tram stops (No.28 to S.Jorge Castle, No.15 Belem). Although we didn't get to meet Sandra, communication was very smooth. Sandra's mum, Maria was really friendly too. We enjoyed chatting with her. It is definitely the place to stay at for anyone visiting Lisbon. Highly recommended!!
