The place was great - good location and a quiet neighborhood with several restaurants and grocery stores nearby. The space was clean, and the kitchen well equipped. There was enough space for all 3 of us.
We arrived around 2 hours later than anticipated, but thank you to the host's friend Rui who waited for us to let us into the house.
On a side note, if driving to Lisbon, there are signs with a red circle for "Low Emission Zones". When we saw these signs as we drove into the city, we didn't realize that the signs were for low emission zones and thought that only Lisbon residents were allowed to drive in. This caused quite a bit of confusion as we tried to reroute. Luckily the hosts replied quickly enough to let us know it was OK for us to drive in.
