Luis was a great host!
We had some trouble finding the apartment, so he and his wife met us at the nearest restaurant and showed us the way.
Even though he was in Lisbon (40 minutes away) at the time we rented, he was always available and checked up on us asking if we needed anything.
He gave us tips about which restaurant to use, which turned out to be the best and cheapest in town, and he even made his family members available for emergencies.
Overall I can highly recommend Luis as a host.
