We were shocked when we got in the flat - that was not as the pictures of this listing showed. The furniture looked very old and it didn't feel as homely and cosy as we expected. Then we realised that the place was very dirty: we found hairs, dirt and dust all over the place: by and under the bed, in the kitchen, in the bathroom and in the count area. There was leftover food in the fridge and the microwave. The bed sheets were stained and in the bathroom we found opened shampoo/shower gel samples from previous guests.
We also found personal documents belonging possibly to previous guests which showed a lot of carelessness about personal data.
The whole place looked it hadn't been cleaned for months and we immediately ran away from it - it was our last week in Tokyo after an amazing trip around Japan and staying here would have meant to ruin the whole trip.
I wholeheartedly suggest not to stay in this flat: you can find (as we did) somewhere clean and tidy for the same price in areas of Tokyo which are even closer to underground stations or the city centre.
