PROS:
Location: calm and quiet but with all the necessary shops near-by (7-11, izakaya, ramen, bars...). Had a feeling of authenticity as no tourists were seen around, just a few expats. From the cars and houses seen around it was an upper class area. The building is above a playground which gives an intimate insight on tokyo local life. The subway (ginza line: very useful for tourists) was 3 minutes away. The closest JR station (free option for JR pass holders) was 15 minutes away.
Flat: so much light! So cute! The bed is just surrounded by windows and because it is on the fifth floor the views are open and nice. The rest of the flat is obviously small (actually it might be big for tokyo standards, i have no idea) but very smartly organised. Everything was super clean. Although in japan many things work differently than in western countries, we were never lost as EVERYTHING was explained in state of the art leaflets, videos and mangas. EVERYTHING!
CONS:
Location: the flat is just too near from the subway and too far from the JR station to actually consider it as an option. So we ended up almost not using our JR pass and spent quite a lot of money on subway (way more practical). Most activity in the neighbourhood (except of course family markt and 7-11) finishes around 11:30.
Flat: EVERYTHING is explained, there was a bit too much information to read/view etc.
CONCLUSION:
We didn’t see the host but was very present throughout, we loved staying in that adorable flat. Would totally recommend it!
