I stayed at Ardenlee Guest House for three nights in February. The owners are lovely and made me feel welcome with a complimentary upgraded room. Check-in and check-out is very easy. The room itself has everything you might need for a short stay: a nice private bathroom, a decently comfortable bed, blackout curtains, a tea kettle, and good, free WiFi. Everything was in nice working condition.
It's nothing fancy, but a comfortable place to stay for a solo traveler. Beware that the walk to the city center, though only 15-20 minutes, is uphill. Consider using public transport (which is all explained when you check in).
