Joana and Abilio's apartment is wonderful! The location is great, just a couple minutes walk from the Baixa-Chiado Metro station, right next to Luis Camões Plaza, and a short walk to the bustling Bairro Alto district. With a 10 or 15 minute walk you can be pretty much all of the tourist areas of the city, and with the Metro station so near, it's easy to get to trains, trams and buses that can get you anywhere. We visited Belém, Sintra and Évora with no problems.
Abilio met us upon our arrival and oriented us to the apartment. They have plenty of information about Lisbon and the surrounding area on the table at the entrance, including many suggestions for local restaurants. We had already been in Portugal for a week before arriving and were getting tired of Portuguese food for every dinner, so we asked Abilio if he could recommend an Indian restaurant. He suggested Ganesha Palace, where he and Joana frequent, and we loved it. If you like Indian food, try it!
