One of the best small rooms we've stayed in was at the Motel L in Alvsjo, Stockholm. We were amazed at how well it was designed. The headboard looked like it went straight up, except that there was a hand hold and when you pulled on it another bed folded out above. The bathroom looked like an artist had done the designs in the shower. The worst room we ever stayed in was at a hotel near the train station in Milan, Italy.
My ideal room would have fast speed internet, a desk with a lamp that had several fast USB ports, a Sleep Number bed with several varieties of covers, sheets, and pillows, a Keurig with a variety of coffee pods, a kitchenette with a microwave, dual sinks, a mini fridge that was placed on a stand so the top was at shoulder height, a rice cooker, a bathroom with toilet paper that did not feel like sand paper, a walk-in shower with plenty of hot water and fawsets that needed more than a tiny movement to increase or decrease the temperature, a plush bathrobe, and double-paned windows that blocked all sound from outside the room.
