It's a bit far from the centre of Lisboa, but good access to public transport. You can walk to the station in 10 minutes, and a train to the centre is 14 minutes. There are shops nearby, but things close early in the area itself.
Ana and her husband were very helpful and welcoming. They respond quickly to help with any issues.
It's good value for the price and has everything you need. It's more old than vintage, though. We had issues with the humidity, but it should be ok in summer
