On the plus side, the location of this rental is fantastic! Close to all attractions and amenities, and within walking distance of the railway station.
Unfortunately, there are many issues with the property and would advise others against booking it. The property itself is not well maintained. About half of the lights in the flat were burnt out, the furniture and furnishings were old and tattered (think student accommodations - that's probably the best parallel), and the bed and cot were old and very uncomfortable. It is also not a clean property. One of our son's toys ended up under the sofa, and we can safely say that it has probably been years since anyone cleaned underneath there. Most of the pots and pans had to be rewashed - in fact, it had probably been some time since the kitchen had been properly cleaned. The WiFi is very unreliable, and would frequently drop-out, and the television in the bedroom did not work.
Again, the location is amazing, but I would suggest that anyone thinking of booking accommodation in York could find much, much better accommodation and at a much less expensive rate.
Generally very clean although the amount of hair in the bath plug hole made me want to heave! Bathroom vent also needs cleaning.
