We stayed at Martin's for four nights and the room was great. Very clean, a nicely decorated apartment and really good to have Netflix! Martin was friendly, quick over messages and really accommodating in letting us pick up our cases later on our last day past check out. It would have been good to have more stuff in the kitchen like an electric kettle and a house manual of some kind. Also, it's worth noting that it's up three flights of steep stairs and might not quite meet your idea of a penthouse!
