Apartment is located around 5 minutes (by foot) from the Tachiaigawa (private) Keisei station. From the nearest JR station it takes much longer, something you should keep in mind if using a JR rail pass. The location is a bit secluded which keeps things quiet. You won't have any problem getting a good nights sleep there.
The house itself is very spacious with bathroom, kitchen, living room and tatami room located on the first floor and three separate bedrooms located on the second floor. So you don't just get one giant bedroom divided by sliding doors. We traveled with three people and could definitely appreciate the privacy. Snoring comrades? No problem!
A convenience store (Lawson, opened 24/7) is nearby. We can't say anything about ramen shops or Izakaya since we always went to Shinagawa or further away for lunch/dinner. But they're definitely there, most of them located around the Keisei station, we just didn't find an oppurtunity to check them out.
Communication with the host was somehow strange. I believe that we communicated with multiple persons. One example: After checking in we asked about clothespin or some other facilities to put up laundry out to dry. Instead of replying to this inquiry we were asked to provide our passports. Something which we had already done way back after we booked the apartment. We then just got ourselves some clothespin from a supermarket.
Apart from this everything went smoothly.
