I recently spent 2 nights in the Melody Hotel in Xian. Without doubt the noisiest Hotel Ive stayed in. Only 4 stories high it is located right on the main square. Location is good with good views of bell and Drum Towers. A hunger busting Maccas directly opposite was a life saver as the "western" breakfast was atrocious. The floors were filthy in the Hotel and it definitely doesnt deserve a 3 star rating. Frankly I've stayed in backpackers with more going for them
The fact that it is in Xian is its only possible claim to fame.
