Private room in architect penthouse flat w/terrace

GUEST BEDROOM AVAILABLE IN FLAT LOCATED ON HOLLOWAY RD, NEAR ARSENAL. IT CAN FIT A FAMILY OF 4 (2 IN THE BED PLUS 2 children ON SINGLE MATTRESSES) but ideally this room is for 1 or 2 people. The scenario of having a family of 3/4 is to accommodate families who are looking for a place to sleep & will be visiting London for most of the day. pls accept the fact that if you request to sleep in the same room as a family it will have a camping vibe & no floor space left to move around :-) The space large private bedroom with double bed and desk. bathroom to share if other guests are staying in the other room.
