We had a very enjoyable stay here, this place had everything we needed in the time span that we stayed and it was a great size for 2 people.
Yuka and the Zen team were very responsive and got back to us as soon as they could if we had any issue's. Everything they had provided us before our trip was extremely helpful (guidance notes) etc. Which made our arrival very smooth.
Overall we had an amazing stay here and would definitely recommend it for anyone travelling to Tokyo.
