Staying at Inês and António's apartment was an absolute pleasure! They were very responsive and gave us lots of tips and information about Lisbon.
When we arrived, tired and stressed from driving through Lisbon (something we urge you to avoid at all costs), our hosts had left some food for us in the kitchen so that we wouldn't have to go back out right away.
We never actually met Inês and António, which is a shame. They invited us for coffee, but we already had plans.
The apartment itself is very comfortable and modern, and it was in perfect condition at our arrival. The location is great, with all of central Lisbon in a walkable distance. You would think it might be noisy to stay smack downtown, but we had no trouble sleeping with the window open.
We would absolutely recommend staying here!
