We had an amazing time in Mas San's apartment in Kagurazaka. The location is beautiful and quiet, and the apartment is very stylish and offers a lot of amenities. Kagurazaka is the perfect neighborhood to explore Tokyo. If you are a couple, you should have no problem with the glass door to the bathroom, otherwise this feature might be a bit indiscreet. All in all, we had a perfect time and would absolutely recommend the apartment.
