What I appreciated most about Chiho and Nuno was their hospitality, they replied (literally, every time) within 10 minutes when I sent a message. They picked us up at the airport upon arrival. We did a tour with Nuno (Sintra, Cascais and the secret restaurant) which was super! It's clear that they only want to advise the best to their guests, they first try places before recommending them. The apartment is great. We visited during the coldest week of the year so it was a bit cold inside and the terraces were of no use but in summer this must be great. A view on the Taag which is hard to find, having breakfast in a sunny kitchen is great. if you love the old neighbourhood Alfama, this is a great choice. If you want to be more centrally located, check out their other apartments as they have several. All in all, I liked our stay and above all the friendliness of Nuno and Chiho.
