I had some personal issue with my check in date and time, and Carlos was really a total gentleman, patient and flexible in accomodating me late at night. The apartment decoration is charming all around; the bed is very comfortable and the kitchen is very well equipped. There were guests in the other two rooms. They were all respectfull to the house rules. The location is awesome, within walking distance to many touristic attractions and two metro stops: Trindade and Bolhão. My only issue was with the building's front door; it was always open, due people not pulling it to shut it completely. If you are a lady travelling alone and is arriving after dark, it becomes a safety concern since the area gets really quiet and not well-lit after business hours. I made it sure to be back home around 7pm, while there were still some people around. Other than that, I had the greatest time in Porto and at Carlo's place! Thank you Porto! Thank you Carlos!
