The apartment is very nice, everything works and it was super clean. Nice kitchen with a good stove. It is well equipped with everything I needed.
That said, it is unfortunately very loud, as it's located under the entry lane of Lisbon airport. They do vary the entry lane every few days, but I had the bad luck to have it over me for 5 days of my 7 days stay, what meant heavy aircraft noise from 6 am to 2 am, with an aircraft starting or landing every 3 to 5 minutes. So after 5 days of only 3 hours sleep per night I was pretty done. Kinda spoiled my stay.
