After driving through the outskirts of Ponce, I was really glad to arrive at Melia - as others have noted, the location can't be beat and you can leave the car in the hotel's parking lot while you explore the city. (Not that the outskirts are "bad" - just filled with American chain stores and restaurants, which I can see anywhere in the U.S., thank you.) If you arrive on a Monday night, as we did, give things a chance - the city was quite deserted and it was tough to find a restaurant that was open. I thought "What the heck was I doing, booking a hotel for two nights here?" The next morning, though, the city square was filled with school groups, vendors, and people hanging out in the park, and much more vibrant. Be sure to walk around and see the different styles of architecture! And be sure to buy your Alto Grande coffee here as opposed to San Juan ($9.59 vs. $14).
Melia itself is quite charming - the Moorish-style tiles and stucco made me think of the Mediterranean coast - but a bit dated. Don't expect the amenities of a larger hotel chain, like an in-room mini fridge, a writing desk, or room service. There IS a business center for guests, though, with internet/fax capabilities.
Breakfast was almost exactly the same fare as a Comfort Inn or Holiday Inn Express - cold cereal, toast, pastries, coffee, juice. (Don't expect hot water for tea or skimmed milk....when in Rome....) On our second day, there was no breakfast at all; I don't know what was up with that! But there are cafes around the square where you can get breakfast. Melia's breakfast is no longer served on the roof, but poolside. We didn't eat at the hotel restaurant (Mark's) so I can't speak to that.
I'd like to go back to Ponce in a few years and see what more has been done to rehab the city and its buildings. At first I thought the city looked a bit bedraggled, but then I came to prefer it over the overrated San Juan. The mountain setting is beautiful, and the people are friendly. We would definitely stay at the Melia, too.
