Sofia is the best host ever!
Before we arrived, she answered all of my questions quickly and always reminded me of the possibility to contact her if we have any other questions.
When we arrived she wasn't able to wait at the apartment herself, but her parents did, and they were super nice. They showed us everything in the apartment and also gave us tips for what to see in Lisbon and for example where to eat good food.
During our stay Sofia still texted me a few times, asking if everything was okay and still giving us nice tips.
I only can recommend staying at her place, it was very clean and everything was better than expected! The area is extremely nice as well.
If I came back to Lisbon, I would stay at her place for sure!!
