The apartment was top-notch. Located a few steps away from a metro station, as well as several important tram stops (Trams 28, 15, 12, and 25), the location made it a breeze to grab public transit and quickly get anywhere in the city. The apartment itself was very clean and modern, and came well-stocked with basic provisions and boutique toiletries.
Miguel was an excellent host. He very kindly met us as soon as we stepped off the metro and helped us with our bags to the apartment. He explained about the important features of the apartment, and took us on a short tour of the neighbourhood. He even had a lovely bottle of wine and a box of pasteis de nata (Portuguese custard tarts) waiting for us on the dining table when we arrived.
While we found the apartment to be very hot the first night, Miguel immediately went out and picked up two large oscillating fans for us to help us stay cool in the Lisbon heat.
I would caution light sleepers (or people not used to a lot of city noise ) that you may find the apartment to be noisy at night. However, with the fans on in the bedroom at night, we couldn't hear any noise from the square.
Miguel was a wonderful host, and we would definitely stay here again if we ever return to Lisbon.
