I was in Phitsanulok for about 1.5 days as a transit point between Sukhothai and Bangkok, and I stayed in Amarin Nakorn during this time. The hotel's location is very convenient, being only within 5 minutes' walk away from the Train Station, Ruamjai Market, the Night Food Market and the Night Bazaar. The folklore museum and the temples, albeit on opposite directions from the hotel, are also within 20 minutes' walk from the hotel.
The quality of the hotel and rooms are of average quality, but for the very competitive price I paid, it was fully worth it. My room was sufficiently spacious and comfortable.
The staff were also very friendly and helpful, and the hotel also provides in-room massage service, which was of very good quality!
