This place is located very well close to Alfama as well as to the downtown core. It is quite a trek to get to the apartment but that is the beauty of Lisbon. The apartment itself is really nice with 2 comfy beds - do note it does get quite cold at night and because it is an older building there isn't much noise insulation, but if you are not a stickler for these then definitely book this place.
Also the hosts even though I didn't get to meet them are super helpful and responsive. Thanks,
Larisa
