I stayed at Mustard Hotel for 2 nights. It was a comfortable stay. Staff are very friendly and helpful. I loved the records that I rented at the front desk. There is a record player in each room and I was able to listen to a record. The only unfortunate part of the location (not a fault of the hotel at all) was that there was so much construction going on around Shimokitazawa Station and the streets can be confusing because of that.
