100% recommend staying here as a solo traveller. It's exactly as described and seen in pictures - a very clean & cosy place with all the essentials. It's a 5 min walk to Hiro-o station or about 15min walk to Ebisu station. 7-11 and family mart is a 2 min walk away which is highly convenient as you can withdraw cash on your way out or back home. The check in process was very smooth and quick thanks to Ruka providing you with the link (by Japanese law you have to register your arrival) beforehand to complete, so upon arrival you just have to scan your QR code on the ipad and you're done! She also provides a clear guide with step by step instructions on how to get to the airbnb and how to use the appliances.
The only "negative" is having to carry your luggage up/down the few flights of stairs as there is no lift, so if you didnt pack light or are weak like i am you may struggle 😂
Otherwise I can't recommend Ruka enough! Thank you so much for a great stay, i enjoyed my time in Tokyo 😊
