It is a lovely apartment, nicely appointed very well located by walking, taxi or subway to all we wanted to see and do. There were 3 of us each requiring a bed so I was the one using the sofa sleeper. I know they are uncomfortable by design as this one was when used for 6 nights. The heat is preset at about 21 degrees C. There were instructions about reducing the heat which we followed but it seemed the thermostat was programmed to return to 21 degrees regardless of desired setting. The apartment was very warm and we all kept the windows open to make it comfortable to sleep. Considering the issues I'd still recommend this rental.
