Although my family arrived late one night and had to leave the next morning, we loved our brief stay in the apartment! Highlights included the private entrance, large spaces, clean rooms, and location in an exciting part of the city. Street noise was significant in the rooms adjacent to the street, but that's to be expected in an urban location. We were surprised at how convenient it was to enter the (unexpectedly large) shopping mall from the nondescript doorway immediately across the street from the apartment entrance. We didn't even realize there was a mall there until we crossed the street to see the children's play structure visible through the window!
We look forward to staying in Telmo's apartment if we have the opportunity to visit Porto again in the future.
