If I were to come back to Lisbon I would 100% stay with David again. Check in was smooth, communication was great and David was a very helpful host. His parents own the small convenience shop on the street and helped make us feel right at home as well. We loved our one week stay here!
We also loved going to the Santa Catarina lookout almost every day, and there is a hip bar called Vago just a few blocks away as well :)
If there is one thing to be aware, Ubers and Bolts cannot enter the neighborhood so if you have a lot of luggage I suggest taking a normal taxi which are allowed in.
