We stayed at Mónica's place for 3 days, and it was the perfect starting point to discover Lisbon. If you want to stay in the heart of the old city, in a cozy and clean apartment, this is the place to stay! The living/dining room has a nice view on the Taag, and the light in the room is magnificent. The mattress is very good, we slept very well!
Mónica has been a perfect host, from the booking until the checkout, I would definitely recommend this place!
