Fernando's place was perfect for a short stay in Lisbon, being very central and within walking distance to lots of the sights and the beautiful area of Alfama.
The apartment itself was exceptionally clean, simple, stylish and comfortable - with an AC, which is needed, as although there are two windows in the apartment both face the concrete facade of the building in front. Also good to bear in mind that there is little to no sunlight entering the apartment - which we didn't mind as we were out for most of the day.
Fernando was incredibly communicative and helpful (although we didn't get to meet him, we did the check in with his friend, who was also very polite).
We were a little disappointed that the apartment is advertised as suitable for three people (indeed we booked for three) and found that the sofa bed had not been set up when we arrived... although there were clean sheets and bedding available, there was not a mattress for the sofa bed so it was a little hard to sleep. Fortunately we were three friends sharing the apartment so we alternated between the bed and the sofa.
Overall a great, clean and convenient base for a short trip in Lisbon!
