Great experience and great spot in the Bairro Alta neighborhood of Lisbon. Cars are able to drive down the street just a heads up in case your driver doesn't know. It is a hilly location (like most of the city) so if you are not able to walk steep grades then you'll need to find somewhere flatter.
The apartment was just as described, open, airy, nice design and perfectly comfortable for our 3 people. The highlight for me was the Miele washing machine. The Germans make good appliances no doubt about that. The balcony was great although it wasn't used much by us.
No real complaints here. It is obvious Susana and company runs a nice business and it shows. Clean, friendly, hospitable, all the things that make for a good stay.
