The apartment was lovely. The location is very central, making it a great hub to explore Lisbon. Yet, the apartment is nestled on a side street and so is pretty quiet, especially the inward facing rooms. The rooms were spacious and well equipped. The garden patio is beautiful, however there would be some restaurant exhaust odors at certain times of the day, which I guess is the price you pay for being centrally located.
Mario was a lovely host and very responsive to communication and easily available (his office is literally across the street).
