I stayed for a little over a week - the location is great, only a 3min walk from Farringdon station. Roy's communication throughout was great. It was very basic and did a job, not the plushest of places and could do with a bit more cooking equipment and a few updates but a comfortable stay nonetheless.
Definitely read the small print re the stairs/no lift! I had a very large case which was a real struggle to get up the very small stairs.
