Perfect place to stay, particularly with kids. Ana was so welcoming when we arrived giving us lots of recommends (and even came to rescue us from a rainstorm when we had no umbrella). The apartment is clean and tidy with everything you need.
She provided everything we needed for travelling with a child - cot, high chair, bath and even toys.
As the listing states, the apartment is up many flights of narrow stairs but we managed fine with a 2-year-old.
I would 100% stay again if we come back to Lisbon.
