I recently stayed at Hotel Del Principado from July 3 - 4th. For those looking for a budget / moderately priced hotel with good service in a nice location, look no further. The staff at the front desk offer great service and are very helpful with advice and travel information. Complimentary luggage storage is available on request. There is a restaurant onsite; however, I didn't have a chance to dine at the hotel. Rooms are basic but comfortable. Beds with firm mattress and clean linen. Simple, Ikea style furniture. A small tv. A very nice bathroom and showers with hot water. Rooms do have worn carpet. The hotel is approximately 10 minutes walk from Insurgents Metro Station and from there just a few connections to the Zocalo. I read previous comments about mosquitoes and was concerned, but I didn't notice any mosquito problems during my stay. The area around the hotel is safe at night and nice for walking with lots of street vendors and restaurants nearby.
