This apartment has a very good location, directly next to the Panteão Nacional. You can basically walk to most sights in the city center by foot, the Alfama is also directly nearby.
The apartment is nice for couples and the neighbors are friendly but sometimes a bit loud.
The communication with André was very good, he always tried to help.
Personal tip: Secure clothes and towels you hang out the window with clothespins, it can be very windy.
