We've stayed at Billy's combo for three nights. The apartment was very clean and comfortable, so were the beds. The bathroom is quite big and also very clean. It was extraordinary hot weather at that time and the living room was heated up during the day (as it is on the top floor, directly under the roof). But we've been in town during the day anyway and with the two air cons we could cool down the two bedrooms at night time so sleep was still very relaxing. We would happily stay at Billys place again if we come back to Boston one day.
