The appartement was well located and well furnished, even makeup remover was at disposal. Patricia was a great host, she shared with us a lot of tips and the communication was easy. You have easily access to all the main touritics locations by feet. Otherwise you can use the subway or the famous 28 tram, it's also close to rossio train station is case you're planning to go to Sintra.
The neighbors is very quiet. I definitely recommend.
