Diogo's flat is in a wonderful location close to the metro,shops,bars,restaurants and nightlife. Despite other observations about street noise as Friday and Saturday's the bars are open very late, once the shutters were closed it was pretty quiet.
The room pictured in which we stayed is lovely, light and spacious. Be aware the toilet is not in the room but across the corridor but for the use exclusively of that room which wasn't a problem. The common areas were clean and tidy although they could be taken over by guests in one of the other rooms which opens onto them.
We would recommend Diogo's place.
