This is the optimum AirBnb experience. The apartment is clean and modern, and the location absolutely cannot be beat. Within a ten minute walk of the front door there must be 30 restaurants, the closest is literally 20 feet away across the street. Shopping is available at a little market directly behind the building about five minutes away. Public transportation--buses, trams, and metro--are literally a one minute walk from the front door. And yet, because you're on the top floor at the back of the building (yes, there's an elevator), you don't hear any of it.
Ana is always available via WhatsApp; I can't think of a single thing that could be improved. We plan to return to Lisbon and wouldn't even look at anyplace else. Don't pass go, don't collect $200; this is the place you want to stay at.
