Maria's apartment is an absolutely fantastic place to stay in Lisbon, whether you're visiting for business/work (as I was, in part) or on holiday. It's beautifully decorated, spotlessly clean and bright, and fully equipped with everything you might need. Cable tv and internet and all appliances work great, the bed is comfortable, and the nights are very quiet. (You can mostly mute the daytime noise from the 28 tram and tourist bustle on the street below by keeping windows closed). As others have noted, probably the best aspect of the apartment is its location, which includes amazing views of the Tejo River--including some incredible sunrises--and of Alfama district below, and easy access to the city center and many major tourist sites (e.g. museums, castle, fado shows, etc.) as well as public transport. The apartment's price may be a bit higher than others on airbnb, but for everything you get it's a terrific value. I was really, really sad to leave!
