Mario is an absolute gentleman. He made us feel very welcome and was extremely helpful. The accommodation was perfectly located. Its on a quiet street that is a 3min walk from Bairro Alto bars and restaurants. 5mins walk from the main shopping area and 10mins walk from the main train station giving access to the museums and beaches.
The apartment itself was very clean with heaps of character, lots of original architectural features etc. The outside patio area is a lovely extra. Given the fact its on the ground floor it was nice and cool. The large wooden doors give an extra sense of security to the accommodation. I would highly recommend this apartment. Next time we are in Lisbon we will stay here or contact Mario to stay in one of his other apartments if it wasn't available.
One other thing – Mario organised a transfer for us to and from the airport. The driver was a man also called Mario. He was a gent as well. He gave us a mini-tour of the city on the way to the apartment and then to the airport on the way home.
Everyone we met on our trip were super chilled and friendly. Already looking forward to getting back later this year.
