We enjoyed our stay and recommend this apartment. It is roomy yet cozy with great views out over Alfama and the river. It has a real neighborhood feel and is conveniently located for the #28 Trolley or for walks all over Lisbon.
Two amazing restaurants are right across the street: We highly recommend Sem (regenerative agriculture centered) and Aura Dim Um Lab. A great gelato storefront is just down the street. Sunny, the shopkeeper next store to the apartment, has snacks and bottled water among other things.
The apartment itself was clean and well equipped and Monica was very welcoming. Our only regret is that we had a slight problem with the living room sofa and brought that to Monica's attention immediately. She was responsive. Beyond that, everything else was just fine.
