I got "upgraded" to a larger room than the one I booked (there are small single rooms at rear, this was a small double at back of house) . Ok for short stay but not for longer periods (only one chair, for example, and the small table has the TV on it). There are bigger apartments to front of house with more space, table, separate kitchen area etc
Small and basic, but with well equipped kitchen, with fridge, cooker, hob, cutlery, pans etc even a dishwasher! There is a laundry in basement too.
Room was warm, comfy bed, hot shower. On 4th floor, no lift (which might matter to some). Is in nice tree lined street of Georgian terrace houses in Bloomsbury. Would stay again.
One thing to note - because this is not staffed in the evening, you have to check in by 8pm (I had a rush to get there after train delay).
