This is a super-cute little apartment in the heart of the "shabby chic" of Alfama (e.g. kitchen window looks out on the derelict building next door). The listing is accurate and the hosts were friendly and communicative. Just a couple of small things to be aware of, in case they matter to you:
Mould: there was a small amount on the bedroom ceiling
Wifi: it struggled to reach beyond the living room
Cleanliness: generally good, but there was some blood on one of the pillowcases
