The apartment was super clean and cozy and has right about everything you need to enjoy a short stay. Antonio is an experienced and kind host who will respond quickly to all your questions.
We never thought too much about going into the touristic areas, as there is plenty to enjoy in this quiet part of town. Lots of authentic Portuguese food around, and if you want, there are some generic hipster places too of course ;) The apartment is very well located to get a feel for the city and within walking distance of most public important bus and tram lines.
The street can get a bit loud with cars, but the windows seal off the sound well (otherwise a good pair of earplugs help).
In short: Great base to explore the city, great host and a lovely neighbourhood.
