First of all, the apartment is clean and with all the amenities you need (and a little extra) to make you feel like home. We (family of 3) stayed for 5 days and we made breakfast ourselves every morning. There is a FamilyMart convenient store just outside the subway exit and a good size supermarket about two blocks away. We go most of our food supplies there.
The place is quieter than I expected as I don't remember any noise from floors above and below us. It is convenient with two subway exits near by, one just 1 block away. The neighborhood is quiet too, seems to be a mixture of residential and a few small businesses.
I had a couple of questions during our stay for the host and he responded timely.
This is definitely a better substitute for hotel! The Google Chromcast is a good touch worth mentioning as we were able to play our own favorite YouTue on TV instead of the local channels.
