To begin with, concerning the house, it was more than great. The apartment has a PERFECT cleanliness, it is spacious, welcoming, bright, cozy to the point that after two days you really feel like home and, to top it all of, the backyard with its delicious fruit trees and grill adds a touch of magic with light. Besides, no need to tell you that it is well located, I just invite you to google the street and you will see that it is perfectly between the beach of Sao Pedro do Estoril (which is great by the way) and the train station that goes from Cascais to Lisbon. In addition, the neighborhood is very secure and even very pleasant (google it and you will have an idea about that too). In short, as regards the house, you can only be pleasantly surprised because it is even better than in the description.
As regards of my host, Cristina, all I can say about her cannot really describe what she was/is. Indeed, she is truly exceptional: warm, helpful, big hearted, generous, amazing kind of person. Furthermore, non only was she flexible on the check in and out, but she also gave us lots of advice about the city and its surroundings. I was coming with my parents and my brother but for personal reasons my family had to leave in the middle of our trip so I find myself alone, but Cristina has been there for me, visiting the city with me among other things. So you should know that she is this really trustful and rare kind of person that I am now proud to have as a friend.
