Carla is very nice - we talked by text before arriving and at the end of our stay, so we were very autonomous.
The area is awesome! Alfama is so pretty and it's super easy to find nice and affordable places to eat.
The flat had everything we needed, I would suggest bringing ear plugs and a sleep mask because there is quite some noise coming from the street at night (it's an animated area :)) and the light comes through early in the morning.
Thanks Carla :)
