Location couldn't have been better: right in the heart of bustling Koreatown, but tucked away in a quiet corner that received very little noise. A five minute walk from Shin-Okubo station. Anything you could need is around the area, from convenience stores to food stalls and restaurants.
Tommy and Shunki were always helpful and very quick to respond. The place was clean and comfortable, with good heating on the colder days. One thing to be aware of: if you're tall, you might have trouble standing in the shower--I'm 195cm and couldn't stand up fully. Not a big issue at all, but just something to know.
Altogether, a great stay, highly recommended. Incredible location and comfortable apartment, couldn't ask for more.
