We had a great stay at Derek's place! Its such a nice location, easily accessible by taxi & train, and it's very close to many great restaurants, coffee shops & convenience stores. I loved staying in hiroo and we slept very comfortably there. We were there in early April and we found the house to get quite cold, especially the lower level, entry, and bathroom. The main wall heater worked great but wasn't enough for the whole floor, so we used the portable heaters but they took some time to warm up and had no English translation for use. I also found the layout to be awkward with the bath and toilet connected to the kitchen- it was very tight and not ideal for privacy. I also wish there was a proper sink in the upstairs toilet room to wash hands and brush teeth. Besides those issues, we had a great visit.
