Nidus is the perfect name as 'nest' is the perfect description for this wonderfully cosy little apartment in Alfama. The neighbourhood is quaint, and when you have the windows open you can hear the hustle & bustle of the nearby restaurants and the music of Fado (for free!). Sara and Jorge were the perfect hosts and made some excellent recommendations for things to do. The apartment was spotlessly clean and we would recommend staying there to anyone.
