Staying at Estela and Pedro's apartment was like being at home for some days: not only their place is charming, nicely arranged and perfect for relaxing after a tough day exploring Lisbon; but the hosts are really wonderful, helpful and welcoming people.
We absolutely recommend "LisbonCore": a perfect place for a couple, in a quiet street of a nice and lively neighborhood, very close to the center and all interesting places by walk.
Thanks again!
