Dear Sir/ Madam,
I am writing to complain about my dissatisfaction with the service I received at your hotel. I stayed here for three nights from the 25th to 27th November this year.
First, your website claims that guests receive a warm welcome, but when I arrived at reception on the first night I had to wait 25 minutes before a receptionist helped me.
Although, I had booked a double room with an en-suite bathroom through the Internet, but there were no en-suite rooms available so I had to use the bathroom in the corridor.
In additions, the website also says the hotel is comfortable and relaxing. But my room was too hot and at night there was construction noise from outside.
I often visit your city and stay overnight. While your hotel is near the centre and therefore convenient, I will have to stay somewhere else if the service does not improve. I hope you will provide better service next time.
Yours sincerely
Dang Thuy
