Bright, nicely decorated, comfortable apartment with good facilities. Not located right in the centre but the area (Graca) is very pleasant and close to public transport, including the tourist tram 28. Naturally it's a bit quieter than staying in the Old Town so we slept well! You can also walk to Alfama and the castle comfortably from the apartment.
Our hosts were as friendly and helpful as you can imagine. There were traditional pastries for us when we arrived and they gave us lots of advice on where to visit. Also they were very quick to respond to our questions during our stay.
We highly recommend as a place to stay!
