With this being my family's first time ever being in Newport, it was a little hard to know what to expect about the location where the house was located, what we could easily walk to, and what was around us.
Upon getting to the Tree House though, we were all pleasantly surprised about how centrally located we were. In one direction we had a main road with the Tennis Hall of Fame, a nice coffee shop, and two different markets to get food and supplies. About ten minute walk in that same direction took us to the Cliff Walk, which was great. In the other direction, you have several restaurants next door to the house and maybe a 5 min walk to the harbor with more places to go/see/eat.
The house itself is great, updated and historic. The one bathroom on the main level is something to slightly get used to - especially with the bedrooms upstairs and the house (obviously as its well over 100 years old) being a bit creaky - you want to ensure that you and your entire party know that going in. Not a negative, just something to plan for in case you need some people in your group to go to bed at a different time than others. My wife and I were there with our two boys under 10, so we had to strategize a bit when they went to bed and how loud we were with the TV!
The angles of the house are very cool and unique. All the amenities that you would need were present, and the dual fireplaces were great on slightly cool nights (even if you could also use the central heat).
Overall, a great place to stay for 4 nights and would definitely recommend for anyone going to Newport and looking for a place to stay within walking distance of all the main attractions. Oh and the parking spots were also key to have as opposed to dealing with being on the street!
