Cheap for a reason!
The Jane is great in many ways - it's characterful, in a great location and the staff are friendly.
The room really is tiny. Think the size of a double bed. But the hotel is very clear about it in advance and there's plenty of space for storage, so I don't think that's a negative
But the hotel does have some problems:
- The AC is very loud, very difficult to control and not very effective. In a tiny room it really makes a racket, and is behind this wooden drill so the remote doesn't really work, and you can't see what it's set to. When you leave the room, you can't leave it running, so you have to have it on when you're in there. I'm a deep sleeper but it got on my nerves badly. 
- The walls and doors are thin. You hear plenty from next door.
- The bathrooms are nice and generally clean. But they are also unisex, and there aren't many for the number of rooms. It's just not what you want in the morning: standing around in a tiny dressing gown, waiting for someone to free up the bathroom.
For me, the problems prevented a comfortable stay. Other people obviously fare better!
