Blue Mansion has lots of tourists. It's an actual attraction, which may or may not be ok with you.
SAVV location isn't very good, IMO, on a busy street.
Seven Terraces is another option. Haven't stayed there, but passed it a lot. Ok location. More modern than heritage. E&O is worth a look, but too big for me.
23LoveLane ticked all the boxes, but don't get a mews room. In these heritage places you want a room in the main house.
