Sergio is an excellent host. We were a bit delayed arriving in Lisbon due to car problems. Sergio was very understanding and made sure to reschedule his other appointment so that he could be at the apartment when we arrived. He took all the time required to show us the apartment and its amenities and to review his very detailed guide book. Sergio also provides you with a PDF copy of the guide book so that you can use it while you are visiting Lisbon. We found it very helpful. The apartment was very clean and comfortable. Location was great. Easy to get around and the area and building were very safe. I will certainly recommend this apartment to others visiting Lisbon.
