Neat and fully equipped duplex in a quiet part of Alfama, within a short walk up or down (or both) to many places of interest. The apartment itself has a living room, kitchen (with a working washer/dryer) and 1/2 bathroom on its first floor (the third from the ground level, very steep steps!), and 2 bedrooms (one behind a curtain) and full bathroom on the second. WiFi works just fine on the lower level, not so much on the upper. No noticeable street noise at night.
A few advices:
When getting to the apartment by taxi, don't give the driver its address, instead, tell him to get you to Igreja de São Vicente de Fora, which is a well known place about one block up from yours, works great! Don't forget to visit this church too, pay a fee for one of the best 360 views from its huge terrace!
A local cafe/restaurant next door great for breakfast or a meal; it closes before 10pm, so not a source of noise.
The famous 28 tram (always crowded) stops 2 blocks away; you have a good chance to catch it not full going "downtown" in the evening.
Communication with the owner and the manager was excellent. We had no issues during our stay (5 nights) - many thanks!
