Catarina and Antonio were great, they waited for me till 1:00 am ! They gave great reccomendations about restaurants and transportation and let us checkout by just leaving the keys on the table.
Apartment was very clean, well equipped and full of everything we needed (shampoo, coffee and even Sagres & Super Bock beers!).
It is very close to city center and some other very nice zones such as Alfama. Overall, it was definately a good stay.
