We stayed at this apartment for a whole week and truly enjoyed our stay. Would gladly take it again.
Our host, António, was responsive and genuinely accommodating. He let us into the apartment, was available for questions before and during our stay.
The apartment's location is wonderful, in a central but quiet street, with nice views through the windows. 5 minutes' walk to Avenida da Liberdade. It is a lovely space to stay in. Tastefully decorated and clean. The kitchen is fully equipped with everything you could need during your stay. The bed was comfortable.
The one exemption to the quiet was the noise from the apartment above, when it is rented, probably due to the wooden floors and thin walls; we could hear every movement of those above us.
We would gladly return, and certainly recommend this apartment if you want to stay in the center of Lisbon.
