Diogo's place was in a great location that was central to numerous places to visit and great train lines. We took day trips to Belem, Sintra, Alfalma, etc. that were super easy based on the location. There are several great restaurants nearby, too. Our only issue was that he was slow to respond to some of our messages, and we had to simply show up to the apartment. (There is a buzzer to Diogo's apartment specifically.)
