We really enjoyed our stay at Cristina's. She went above and beyond to accommodate our schedule and was very easy to communicate with (quick at replying to messages).
Her house is exactly as her pictures show. We weren't expecting Lisbon to be so hilly, and ended up having a super fun tuk tuk ride up to her place as it's on a hill!
Her friend, Anabela, met us at the airbnb and was very thorough in explaining everything, as well as providing recommendations. The beds were very comfortable. Living room was a little chilly in the evenings despite having the heater on - that said, this didn't bother us very much since no one stayed on the sofa bed! The heaters in the bedrooms were brilliant and we were kept toasty through the night.
Hope this helps. Obrigada for a wonderful stay Cristina and Anabela!
