We arrived at the apartment early but Paula was happy to let us in to dump our bags. The apartment was very clean and well equipped - we were pleasantly surprised to find an excellent bottle of wine waiting for us. The coffee machine was a bonus and well stocked with refills.
The location was great (it did get a bit noisy at night) with loads to see, and plenty of places to eat within a few minutes walk.
We would definitely recommend Luis's apartment and we would also recommend Lisbon.
