Located right behind the Saō Bento station but in a quiet back alley, the apartment is both very central but also out of the pathway of the tourist hoards! It's freshly renovated and has an elegant and smart practical design, which is essential for comfort in a relatively small space. Also, it's by far the best-equipped AirBnB I have stayed at in a long time in terms of real-life utensils, like cooking and cleaning appliances! Bed comfort is a very subjective thing - I like stiffer mattresses and found the one in the apartment just right for my taste.
On the minor criticism side - the house next door is currently on reconstruction, so depending on when you're reading this there might still be some noise coming from the site over the day. The windows of the flat are super-soundproof though, so with them closed you barely hear any of it. I also imagine that in summer it might get rather hot in the flat, but I cannot judge from my own experience...
All in all - many thanks to the owners for a wonderful stay!
