We enjoyed our stay at Oliver's place, and can share the following about it.
Pros: communication and self-checkin were good. The location is within 7-8 easy walking of Farringdon station (both tube and railway). Few bus lines that we used were also near. The place was clean, beds were very comfortable, and in general we found it to be a cozy place for our family. Small supermarket as well as restaurants close-by.
Cons: the bathroom was sub-standard, missing some essentials such as mirror (had to shave "blindly"). The windows aren't sound insulated so in the mezzanine room we could hear A/C motors and in the front room could hear activity in the alley.
