Yuka's place was a great stay. I stayed for a week with my girlfriend and it had everything we needed. Everything was very clean and worked well. Zoshigaya station is a 3-4 minute walk and made it easy to get around. The area is very quiet and feels safe, there is a convenient store nearby but everything else you need to walk more or take a subway to get to. The space is very small for 2 people but it was cozy and was perfect for our stay. I definitely would stay again. My only complaints are that the pocket wifi is extremely slow but it was included with the room and was enough to help me navigate the city and receive and send texts and emails. My other complaint is that the towels smell a bit strange. After we shower we hung the towels to dry and a strange smell came from it. You could just bring or buy your own towels.
