My friend and I spent a week in Maria Rita's apartment. It was pretty much as described and as the photos show on the site. It is situated in a beautiful neighborhood that is around a 20 minute walk downhill to the Baixa/Chiado area - the city center. We felt very safe and the apartment had all the basics that you would need. Maria Rita was the perfect host. She welcomed us with a bright smile and spent a good hour with us I would say, going through Lisbon's map and pointing out the endless activities that we might enjoy. She offered tips, suggestions, excursions, train/metro directions and so on. A few days later she emailed with a list of Fado venues - with detailed comments one each suggestion. And later on emailed back with a list of restaurants and bars.
All in all it was a beautiful stay, if I were to suggest any changes, it would be to simply hang a full length mirror somewhere. It would have been handy for us two women ; ) .
