This place was in a perfect location in Alfama. My husband and I stayed here in late December - early January. The hosts were extremely responsive and helped us book transportation. The pictures also matched the apartment. There were plenty of amenities, and there was a drawer full of maps, recommendations, and information about Lisbon/the apartment.
We are used to a bigger bed back home (this bed was equivalent to about a full-sized bed in the states), so it took some getting used to. If you are a light sleeper, I recommend earplugs because the place next door has stairs above this place. You can hear people going up and down the stairs and walking around.
