The apartment is located in Alfama, which is truly a great place to stay. It's about 5 minutes from the Metro, and has several Fado bars/restaurants nearby which makes nightlife interesting.
We found the apartment clean and tidy, having everything our hosts listed on AirBNB. The kitchen was great - we made breakfast every day which was really fun.
In conclusion - we recommaned Sueko and Mafalda's aparment. It's a great place with a fair price.
