Me and my sister (23 & 16 years old) stayed in the apartment for 4 nights and had a nice time in Lisboa. The apartment was like in the description. The kitchen was very clean, we just missed some more/bigger pots. The bathroom had a bad smell.
The location is very close to the centre and we could reach almost everything by walking. Sadly we didn’t felt that safe in the neighbourhood because of people selling drugs near the apartment. At night it was very loud. We would recommend the apartment for adults for a short city trip without children.
