The hosts were extremely communicative and guided us well during our recent 4 night stay in Lisbon. Their recommendation helped us experience us a Benfica game in the stadium which was the highlight of our trip.
The location is great in the old town Alfama area. The house is quite good for a 300 year old building. The only thing I wish the listing mentioned was that the building and rooms are slanted. I have vertigo and had a very hard time with loss of balance. My family clearly noticed the slant as well and found it hard to navigate for a 4 night stay.
Lisbon in July gets hot, so without AC even though the fans and keeping the window doors open helped, it gets really noisy all night with trams and garbage trucks and other vehicles, so we did not get good sleep. Just something to be aware of.
