Here's another in the same vicinity. Looks a nice guesthouse. And has a good write up which I'll post underneath the address.
Glenroy Hotel
192 Stow Hill
Newport
Monmouthshire
NP20 4HB
Wales
The hotel is a combination of old and modern design. Newport itself is one of the 'new towns' going for City status, and has many fine examples of modern architecture. Newport attracts Speedway fans, and with Cardiff only 15 minutes away by train, fans of many other sports too.
