The apartment is a one-floor walk up, located in a lively and nostalgic part of Lisbon. The space is big and comfortable, with the old charm expected from homes in the area. The common areas were very generous in size, with lots of room in the living and dining areas. Bedrooms were a good size too, except maybe the 3rd room, which was abit small and tight.
We were met during check-in by Cidália's son who warmly welcomed us with information, tips, instructions and delicious pastiles and port! The apartment facilities were good, with a fully functioning kitchen and a washer that worked well. The bedding and linen were comfortable, and there were stand-fans in the rooms for nights that were warm. Air-conditioning in common areas is available. There's one bathroom with hot water available at all times.
The street the apartment is on has many restaurants and bakeries, plus a small supermarket up the road. There is a good list of recommended restaurants nearby. It's a good uphill walk to the main Chiado-Baixo metro station, which connects you to basically everywhere. Getting to the and from the apartment from the airport was best by Uber, as navigating the narrow cobbled streets with luggage isn't the best idea.
The Santo's apartment is a good choice while in Lisbon. It is walking distance to many attractions, and is a short train ride away from everywhere else. Tram 28 runs infront of the apartment, and that gets you to most places, but it's always full! Best to get yourself a day pass if you plan on using public transport.
