Having visited York many times over the years, 12 St John's Mews is certainly one of the best self catering accommodation we have stayed in. Stays York manage several properties in this development and we think this is possibly the best. The apartment is very light, tastefully decorated and furnished. It is on the first floor, with views of the Minster from the living/dining/kitchen and one of the bedrooms. The second bedroom is also very light with double aspect windows + juliet balcony. There is also a juliet balcony in the kitchen area. There is only one bathroom (only a shower) between both bedrooms. The parking bay for this apartment is 8. The car park is supposed to be accessed with a key fob to lower the bollard, but on arrival the bollard had not been working for some time (according to a resident), so the fob isn't needed. The apartment is keyless with a digital entry system on the door.
We had actually booked the previous 7 days with Booking.com and loved it so much, we extended our stay by three nights directly with Stays York.
The only problem we had was the hob which is an induction one, but the saucepans provided weren't suitable.
