I was in Chiho and Nuno's house with 4 friends for 3 days and we had an amazing time. Although we didn't meet Chiho she was really helpful with her indications and also offering help before we got there. We arrived so early in the morning and although the apartment was occupied, Nuno picked us up at the airport and also took care of our luggage until we could access the apartment in the afternoon. He was really really nice during all our stay and even took us to a beautiful day at the beach!!. You could not expect more of your hosts, they were the best.
Also, the house is just as it is shown in the pictures and is localted in beautiful Alfama, a neighborhood you shouldn't miss when visiting Lisbon.
We totally recommend this place: with Chiho and Nuno as hosts you will feel at home!
