The house in general is a bit old, needing some cosmetic repairs in a few places, but overall clean, pleasant and charming. The room is very cozy, with a large and very comfortable bed. The only (minor) weak point is the bathroom: to take a shower, you need to turn on the water heater in advance. Also (didn't bother me at all, but maybe it is worth mentioning) it has one of those old British/Irish sinks with separate hot and cold water taps.
However any minor inconveniences of this sort are completely trumped by the hospitality and generosity of the host. Alison has been very kind and welcoming with me (as well as with the other, longer-term tenant: a student from Japan) - offering lovely conversations, a couple of beers, and even cooking us dinner one of the evenings. It has been a great pleasure to stay at her home; I can only recommend it!
