We are 2 couples in our 50s and picked this apartment for our first ever Airbnb. Communication with Sara, our host, was almost immediate every time. Sara met us at the apartment with lots of tips and a little gift. The apartment is clean and airy. One bedroom is downstairs and you can close it off - great for privacy. The upstairs bedroom is smaller but perfectly fine for 2 people. There are 2 full bathrooms, both with a shower and plenty of hot water. Shampoo, conditioner, shower gel and toilet rolls are supplied, as are basic kitchen supplies. We didn't really use the kitchen but it has all the equipment plus a coffee machine. There's a supermarket just around the corner where you can stock up.
It is in a quiet area but lively Bairro Alto is a 10 minute walk away and we spent our evenings eating and drinking in the lovely restaurants and bars. The location is great; everything is pretty close by, including the tram stop for the famous tram 28. I would recommend this apartment to anybody for their stay in Lisbon.
