We had an enjoyable 3 day stay at Sofia's apartment. The apartment is well located, making it ideal to walk to most sights in central Lisboa. Plenty of restaurants and bars in the area, although we had no issues with noise at night. Only areas for improvement would be the comfort of the bed, and lack of toiletries in the bathroom.
While Sofia was not around to welcome us, she was very communicative and accommodating with check in and check out. Much appreciated!
