The place was super clean, Ana is an adorable person, very helpful and charming. We found the location of the apartment very good for our daily trips. LX Factory is literally in your back garden, we spent there almost every evening.
If you are a sensitive sleeper I would recommend to bring your earplugs as Lisbon is not the most quiet city but that's why we all come to see it, right ;) As well, the apartment is located on a busy street with trams and buses.
