We stayed 4 nights at Dino's place and it really felt like a home within a very vibrant city. It was quiet at night, had everything we needed including a free car space and washing machine, and had funky design.
Dino was lovely and a great communicator! We would recommend getting fit enough to walk this Alfama neighbourhood as it is full of personality and great photo opportunities. Walking tours of the historical centre and Belem (find the pastries!) are also a must as they help you orientate and immerse yourself in this quirky place.
Our only issue was that we found the drive in the city centre to the apartment quite overwhelming particularly as we aren't experienced drivers in Europe. If you are driving we would recommend arriving outside of the regular tourist hours (before 9am or after 7pm) as we had to navigate around trams, traffic and tourists as the location is right in the castle walls.
Other than that we could not fault this great apartment.
