Nice quiet stay for a visit to nearby family. Everything was fine for my visit, staff were very friendly and went out of their way to help. Command of English was poor, however I managed fine using Google translate.
No recommendation for anyone to stay in this hotel
I booked a deluxe sing big bed room. But what I stayed was a room without windows and bad smell in the room. Apart from this, the restaurant in the hotel was not open to the guests during the lunch time. The reason was that they were entertaining a delegation. This is ridicules.
