We did not meet Diogo but he responded quickly to all messages and key pickup went smoothly. The flat was large, attractively furnished, well set-up and in a very convenient location. However, it was very noisy, all the time, because street carried a lot of traffic. We wore earplugs when inside, but even they did not block out the sounds of cars/buses on the cobblestones at night. And the windows had to be kept closed because of the noise.
