We had a lovely experience with Ana and her husband Pierre. They are excellent hosts and the flat is well equipped. Ana is super responsive and kind and even hooked us up with a great Dyson heater—Lisbon was experiencing a cold front when we were visiting. They left us a bottle of wine, fresh bread and some lovely nibbles in the fridge.
Unfortunately, the upstairs neighbour is a struggling addict and came to our door three times, once at 11:15 at night to ask for money. Later that night we were also exposed to him loudly masturbating above us. It made us really uncomfortable and we left the next day, instead of staying for three more nights. I know Ana doesn't have control over this, but I think other travellers, especially single women, need to know this before booking.
