I loved it.
The city is very old (like most things in China) and is encased by an impressive wall, in the centre you will find the Bell Tower and adjacent to this is the Drum tower. We caught the bus from the airport to the city centre (if you're catching the bus, be sure to get the one that goes straight to the Bell Tower) I can't remember the exact amount we paid for the bus - but I think it may have been 50 RMB (about $8 AUD)
We stayed at the Han Tang Inn Youth Hostel - which I highly recommend - The hostel was more like a hotel. It was the BEST hostel that we stayed in, in China, and to be honest - the best hostel I have ever stayed in. It was 200 RMB ($31 AUD) for two people per night for a private twin room with en-suite - Thats about $15 each! AMAZING.
In the city centre is a giant people-mover round-a-bout. Many a time did we get awfully confused in here - It is underground, so you don't have to negotiate the street traffic - just remember which exit to come out of. We found that there were not very many Westerners walking around the streets - which we loved to do, taking in all the sights. Which was kind of nice.
The Bell Tower gives you a fantastic 360 view of the city and they also have musical performance on. The Bell Tower will set you back 30 RMB ($4.50 AUD) and you can buy a joint ticket to check out the Drum Tower too.
Xi'an is also the 'base-camp' for tourist visiting the Terracotta Warriors. Most people tend to send no time around Xi'an or the neighboring towns. I recommend taking a few extra days to explore. There are some really interesting sights and things to do.
