I thought there was plenty of room, including bathroom space, in the 1 bedroom. It's split--with a sink and tub in one large area, shower, sink and toilet in the second area. We were there with a family of 5, including a 15 year old teenager, 11 year old, and a toddler, and had no problems. With the 1 bedroom you also get a big balcony with table and chairs, plus the large living room area. Don't forget you also get a laundry room with the 1 bedroom--very convenient to throw a load in at night vs. schlepping down to the laundry room with dirty clothes and waiting. Guess it depends on how you'll use the room. My dh liked the kitchen table for getting some work done on his laptop; it seems a lot less "hotel like" than a studio. JMHO
