Our stay was very pleasant. The apartment was a little small and the ceilings were low but the location was great. About a 20 minute walk to the city center and our hosts gave us great places to visit near the apartment. The place was super clean and the balcony was a great plus.
The only complaint I have was the circuit breaker always tripped when the oven and stove were on at the same time. We had to unplug everything to be able to cook our meals.
With that being said, Lisbon was one of my favorite countries to visit and our stay was fabulous. The hosts were accommodating and let us keep our baggage at the air b&b until we had to leave for our 9pm flight. Very nice people with a very nice location.
