First, Nakameguro is a fantastic location. Very chilled, with lots of boutique restaurants and shops 1 my favourite area of Tokyo so far. Riko’s place is literally a 5 minute walk from the station. The pics didn’t do it justice, very cute airy place, extremely comfy bed, super soft towels and powerful shower - I would highly recommend staying there. Riko was incredibly helpful too. If you bring earplugs you won’t hear the nearby trains.
