We have just spent three nights in Ana's lovely apartment and cannot recommend it highly enough. It is situated in a quiet area with a few restaurants around we had a lovely meal in a Greek restaurant around the corner called ilhas gregas on the street rua das trinas.
You can walk into the centre downhill in about 15mins but we got taxis home the hills in Lisbon are steep taxis were around 5euros.
The apartment is lovely and just like photos the view from the terrace is great.
When in Lisbon the tram 28 is a must but gets very crowded the best way to see the city is to catch the 25 tram around the corner and down the hill from the apartment get on the same side as the little cafe and not the small supermarket take it to the end of the line to the cemetery which is the end/start of the 28 route if there is a bit of a queue it is worth waiting 15/20mins for the next one so you get a seat and take in the city.
Thanks Ana loved staying in your apartment hope to stay again one day
