We stayed in Hugo's apartment for four nights. Samir met us at the apartment even though we were slightly later than we had said and he was very helpful showing us where everything was.
The apartment had everything that we needed, although if we had tried to cook a meal in the kitchen it probably would've felt slightly cramped. The bedroom was spacious, nicely decorated and had nice views of the church and castle. Unfortunately, for the first two days we were there the temperature reached 40 degrees and as there is no air con it was very hot at night (however, this was in the middle of a heatwave so would probably not be a problem in normal circumstances).
It is located very close to the Martim Moniz metro station and is within walking distance of all the main sights including the start of the Tram 28 route (very good experience but we witnessed two people get pick-pocketed on the 40 minute journey so be careful!).
Overall, a good apartment for the price we paid and a great base to explore a wonderful city.
