I would 100% recommend staying at Aki's place. Although it is not "close" to the station, walking to her house gives you a chance to look at Japanese lifestyle. Aki is very kind and thoughtful host, she replies very quickly to any questions or concerns you have. She will also make food or place suggestions which is very helpful if you want to explore the area. She is a very tentative host! The pictures are true to what the room looks like, very neat and clean. It is a good amount of space for two people. If you are looking for a place away from the crowded and loud city, I would totally recommend Aki's place. Shibuya is not too far so you can still be close to an entertainment area.
