We just finished a three night stay at Karen and Will's place in Portsmouth. We travelled from Denmark, but I am familiar with the area because I used to live in Portsmouth, right around the corner many years ago.
Karen and Will were great hosts. They were fast to reply when we had inquiries before our arrival, and very thorough in providing us with all the information we needed for our stay. They gave us a nice welcome when we arrived.
The apartment was big, up-to-date, and very clean. It looked like new but it still has the charm of a typical old town apartment. I have used both Home Away and Airbnb for other stays; this is by far the nicest place.
It was a perfect location for my wife, two kids, and me. It is in a nice friendly neighborhood and close to everything you need. There is a shopping center with a large grocery store and convenience store just down the street. There is a nice playground for the kids up the block. Best of all, it's an easy 5 minute walk through a nice area to downtown.
We a wonderful stay, and couldn't have asked for anything more. We are heading back later in the year, and will try to stay here again. I can highly recommend it.
