Communication: Great! But I only communicated with the host PRIOR to me coming as I didn't have any issues during my stay. :) One thing I really appreciated was the PDF file that Hiroki sent me before I came. Literally has pictures and instructions on how to get to the actual room as the room itself is inside a hotel (the room isn't part of the hotel though, a bit odd). Also instructions on how to get the key, how to use the AC, and how to use wifi.
Pros: Room is very clean, spacious, and cute. I liked it! The bed and pillows were comfortable! Sort of a nice view on the balcony, sort of. AC was awesome and worked like a charm. Fairly quiet room; didn't hear nonsense from the neighbors.
Cons: AC is LOOUDDDD. I didn't have a problem falling asleep though but that's just me. The walls are a tid bit thin so you will hear people's door slammed closed (although to be fair, didn't happen the entire day, just maybe once or twice a day I'd hear it when I was actually in the room). If the next door hotel plays any music in the yard, you WILL hear it. A little annoying but luckily, they didn't go late into the night. PARKING SUCKKS.
Parking if you're planning on renting a car: Although, there is "no" parking, you CAN go to the front desk and ask them if you can purchase the nightly pass (in and out privilege) if any is available, but it's $35 bucks/night and may not always be available depending on how late you decide to purchase it. Neat thing though.... during the day time, they do have free 2 hour parking in the garage but you will need to write down your car information/room # with the front desk. And if you think you're going to get street parking, good luck. It's a nightmare finding free parking on the streets after maybe 3 or 4pm. There are some meter parking around but it's either $1.50 - 3.00/hour, usually till 10pm.
Overall, enjoyed my stay. :)
