Great stay - right between two main stations - Roppongi and Azabujuban so getting to places is pretty easy and you have options of how you want to travel around Tokyo. This area is surrounded by izakaya and is a little bit rowdy after dark on drinking nights, but we're heavy sleepers, so we were not bothered. The owner is very pleasant and met us in her office. If you want an authentic Japanese downtown living experience - this is a good one! No laundry in suite, but there is a 24h laundromat very close. There is an elevator, but it's tight, so just be aware with large bags and multiple people. My husband and I with two medium suitcases fit snuggly.
Also! Be sure to check out Mont Thabor bakery, about a five minute walk - try the milky bread! It's heavenly!
