Maria's apartment was a great spot to stay in Lisbon - conveniently located in Graça near the 28 tram and the lovely Cafe do Monte, with an unbeatable view from both balcony and living room.
We had no issues with the apartment - Maria's friend Candida met with us and got us settled in; there was a bottle of wine waiting (a very nice touch!); the kitchen was stocked with everything we needed; and the flat appeared just as in the photos. The in-bedroom shower is a little odd, but wasn't a problem for us. Hanging clothes to dry on the balcony was vertigo-inducing for me, but having the washer was very helpful! Maria also has an extensive, informative guide to Lisbon, and some copies of Time Out and other travel magazines that we made good use of.
Like other reviewers have said, the only real con is the price you have to pay for the panoramic view - at the end of a day trekking up and down Lisbon's hills, the fourth-floor walkup occasionally left us panting, but well worth the sunset vista.
Overall, had a lovely time here, and would absolutely stay with Maria again next time we're in Lisbon!
