Stayed at the site for 4 nights in early August. Our first time at the this site and found it to be a pleasant and convenient place to spend a few days. Wardens as always were very friendly and helpful. I found Tredegar House was much more friendly and relaxed than many other stately houses we have visited and grounds are well worth spending some time just walking. The site itself is well situated for exploring Cardiff and the surrounding area. There is some road noise, being so close to the M4, but we did not find this to be overly intrusive and I would not let that put you off spending some time at this wonderful site.
