Very clean and beautiful apartment, very well located to visit Lisbon. Close to the underground and you can easily walk to the old town touristic destinations. The only minor downside for us was to take our son pushchair up and down the narrow stairs, but overall I would recommend Ana & Mariana place and I would go back if again in Lisbon. Check in and check out was particularly good, with transport arranged to and back the airport and a very convinient locker to store the luggage after checkout.
