This is a very nice apartment, located at a convenient neighborhood in Lisbon. We are happy with the amenities in the apartment. We don't get to meet Catarina, rather all the service was provided by a concierge, who is very nice and friendly. We actually were not able to reach Catarina by phone, as I realized that I left my ring in the house by the phone number in the record. Luckily the concierge and the cleaning lady came to the rescue. So, it still turned out to be fine.
The downside is that they don't accept any early check-in or late check-out. If you arrive early, you need to be mindful that you will need to pull your suitcase up and down the hill for a bit.
But all in all, it was a pleasant trip, we enjoyed Lisbon and the apartment.
