We had à wonderful experience at Inès and Bruno's place. They were both very welcoming and we had some very nice chat about Croatia and Portugal among others! Only little thing though for my wife was the temperature (but we were there in february)... Sintra is cold and humid! (but also amazing), and we really needed the personal heater and extra blanket. But we also realized since then that it is the same everywhere in Portugal, no central heating!
Anyway, thanks to both Inès and Bruno, we will recommand their place for sure to our friends.
