The place is in a very good location as it is close to all attractions and restaurants. It is very well equiped. The communication with the host is very good. There was a leak in the water heater but we were warned in advance and it was fixed quickly. The hosts are very responsive and make sure you are informed.
The apartment is very nice and clean although it is much smaller than it looks in the photos and I would rather call it a studio/room.
Although the neighbourhood is much calmer that a few streets away it is still very loud and we kept being woken up by neighbours/people walking by/people collecting trash at midnight/taxi driver at 2am trying to get out backwards up the hill..
But this is Alfama and you should keep that in mind when booking in this area.
Anyway, I would recommend this place for solo/couple who want to explore the city and enjoy the night life.
