We stayed at Ai's place for four nights in November and were very happy with our choice. It is clean, well equipped and was just what we needed for our visit. The location is great and balcony views were just like the advert. The only slight issue was occasional noise from construction work from a similar floor on the next building but it stopped around 4pm and at the weekend. Ai was a very helpful host and responded quickly to our messages.
We would definitely recommend this apartment to others.
