Bruno and Flavio Andrew at Gem accommodations were very responsive to all my inquiries and provided top-notch service our entire stay. I would especially like to mention that John (João) who checked us in and out of the apartment, was great! He was extremely responsive to all our questions at check in and provided us with great tips on things to do and places to eat. He was also very responsive when we had a power outage at the apartment on our 2nd day there. He got a technician to respond immediately and then stayed with him until the power was put back on. We could not have asked for better customer service. The apartment itself was very modern and clean, with all the amenities we needed (e.g. air conditioning, washer/dryer unit, great wifi, comfortable beds). The apartment location is in the heart of Bairro Alto, the nightlife center of the city and the perfect location to explore Lisbon. While the noise from the nearby bars/restaurants went on late into the night, it did not bother us as we specifically chose to stay in Bairro Alto to be able to party late into the night and then have a short walk home. Obrigado to Gem Accomodation and John for such helping make this a great stay in such a great city.
