The apartment is pretty small but perfect for one person, maybe also for two if nobody is too "large" ! It has everything you need for a short holiday in Lisbon. It is located in a lovely area of the city, it seems to be in a little village and I loved that. The houses in the area are very close to each other, so you can hear most of people talking in the street and your neighbours, but for me that was something that give a character to the place. It's walking distance to the centre with lots of attractions and in the evening there are noisy bars and restaurants, much different from the area of the apartment's of Navina... which is also surrounded by very good restaurants and bar to eat local food.
Even though I haven't meet Navina in person, she has been always present via messages. I would come back here for sure.
