First time using Airbnb and I think we have been spoiled. The flat was clean, well laid out, and the yard was a godsend, especially considering we had our 1 year old. She spent every morning and every evening running around playing. The neighbors probably hated us with all of her laughing and screaming, but she loved it.
The location is central to both public transportation and walkable areas of interest, without being in too "touristy" of an area. I think the longest we had to walk anywhere for dinner was maybe 15 minutes. There's a botanical garden 10 minutes away, approximately 5 or 6 other quiet little small squares to relax in, and a miradouro (look out point) just a 5 minute walk up the hill.
Oh, and the bakery that is only about three doors down? You'll walk there every morning for pastries and rolls. They're amazing.
