It´s location is perfect, it was my first time in Guadalajara and everything was basically walking distance.

What I did not like was the restaurant service, which took almost 10minutes to get me an orange juice, not to mention I had to ask for a waiter twice, coffe was never offer and after 20min my breakfast did not arrive, so I cancelled and left, bummer... pool was not clean on my second day of stay.

We just got back from 5 nights at the Hotel Cervantes. It is very conveniently located in the historic center of town. The street is busy at night, so we did not feel in any danger out at night. It is in an area of gay bars, but that didn't bother us.
Our room was fine, the air conditioning was almost too cold! Beds were comfortable, there was ample hot water and water pressure.
Our room was not a street view and was quiet.
Hotel worket Martin (bellman, security, etc) was veryhelpful for everything from restaurant recommendations, helping with a balky door lock, and even helping our friend who had a flat tire while visiting us at a hotel. He was able to provide the name of a nearby tire repair shop open on a Sunday afternoon.
We found a price on-line of about $50/night and felt we got a great deal. Free secure indoor parking, and free wireless internet were a plus!

I stayed here with my partner over night after arriving off the bus from Mexico very late at night. The room cost us A$73 and it was terrible for that price.

Firstly the airconditioning was broken and rattled all night. The only reason we kept it on was because it was hot and it was better than nothing. The green carpet felt like it hadn't been steamed cleaned in years and I was actually afraid of putting my bare feet on it. The bathroom was dirty and in need of a clean. When we turned on the shower tap, brown stuff came out that looked like rust and dirt. The whole hotel just felt dirty.

Now I'm not a picky person however for the price I was very very diappointed. I've stayed in places half the price and about 4 times better.

Avoid this hotel at all costs. There are better places to stay in GDL.

stayed at cervantes for (1) night only, and that was due my late arrival. checked out the following morning.

pros:
cheap rate (under $75)
central location
free wi-fi
clean bathroom/linens

cons:
no smoke-free rooms (first room smelled smoky, second less)
no in-room safe
no fridge/mini-bar
no hair dryer
no alarm clock
no iron/board
no hot water (i was so tired, at this point i didn't care)
worn-out, beat-up sofa bed

TIP: 3-stars/mexico is NOT THE SAME as 3-stars/USA
