There's definitely some real pros and cons with this apartment. Firstly the location close to Shinjuku / Shimokitazawa / Yoyogi Park / Shibuya is so convenient - basically walking distance. However the apartment itself is right next to the raised highway which is extremely loud. Be prepared for constant traffic noise. The apartment inside is great, has everything you need for a short or extended stay, probably one of the best bathrooms I've stayed in Tokyo. The bed was a bit uncomfortable and the main issue was the internet didn't work half the time I was there, but I think the issue has been solved now. Overall a great location if you can bear the traffic noise, also the Zens Team are super helpful and responsive !
