Silvia's place is just a few blocks from the Biaxa-Chiado metro stop, so you are right in the middle of the tourist area of Lisbon. The location is perfect for exploring Lisbon, and the apartment feels like someone's home rather than a hotel or hostel. At night, you can hear the live bands from the restaurants below, but they stop quite early (maybe around 9 pm?). Silvia also left us a bottle of port wine and some fruit, which was enjoyed and much appreciated! As others have mentioned, the apartment is on the 4th floor, so be prepared for a few stairs. As a word of warning to anyone who is a magnet for mosquitos (like I am), we did get some mosquito bites sleeping with the windows open, so be prepared!
