We stayed at this house for 3 nights in early September and it was beautiful, just as the photos had depicted. I was pleased to find that despite the age of the house there were standard 'mod-cons' such as hair dryer, wifi and air conditioning - although our air conditioning wasn't particularly effective in the 40 degree heat!
Everything is in keeping with the age of the house, which means that the doors don't close 100% perfectly and the blinds allow some light in - neither of which are a problem at all until it's dark and you have the lights on in the room and then you lose a lot of privacy as others can see directly into the room from the communal areas.
I was apprehensive about sharing a bathroom with others but it didn't cause us many problems - I think we had to wait for a shower on one occasion only.
The location is absolutely perfect, just a few minutes' stroll to the Cathedral and all other main sites of the City.
