João was very accomodating and responsive. We never met him but all was well communicated and explained thoroughly.
Unfortunately the apartment has a distinct damp smell. It is smaller than the photos would make believe and one of the glass fronts doesn’t have a curtain. The ‘terrasse’ is that place at the bottom of a building above which everyone else hangs their laundry (and apparently wet carpets).
But: great location, literally 3 steps away from a popular spot for sunset watching over Lisbon.
We stayed one night and for that it was OK.
