Excellent place, loved it from the moment we came up the stairs, the stairwell being really nicely decorated. The flat is also decorated in a stylish fashion, very welcoming with a nice living-room, practical kitchen and 2 shared and clean bathrooms. Mariana greeted us when we got there, showed us the place and made us feel welcome from the get-go. The room was simple but beautiful, with a small balcony that you can even see the street and river in the distance! It does get cold at night in November so maybe that's something they can look at but we did get a heater for our room which made it bearable. To get to the place you do have to walk up a hill for a bit, but that's all of Lisbon really, you'll have to do that.
All in all a great experience and excellent value!
