I'm not sure where exactly others stayed but my stay was absolutely fine and for some to say it's not near the beach is ridiculous. The beach is just 4-5 minutes walk away. The Hotel Marbel is a 3 star hotel, my room was modern, looks like it had been refurbished as did all the others I noticed daily as they were being serviced. No tea/coffee making facilities and no fridge which I did struggle with as the weather was very hot during my 5 nights. However, excellent air conditioning and easy to use. My room and bed was comfortable and the bathroom also quite new. I slept very well throughout my stay, no complaints about my accommodation at all. There is a small roof pool and some beds to enjoy the sun but the beach is just minutes away so the choice is yours. Wi-Fi is free but to be fair only really works in reception. Breakfast was a choice of continental or hot cooked (eggs, bacon etc.), and rolls/bread/fruit/drinks, not the greatest of quality but topped up when needed and edible, you shouldn't go hungry.
The hotel's location is perfect, just off the main road, 6-8 mins from the airport (bus 21 @ 5 euro's each way). You are surrounded by shops/restaurant's and bars and more along the beach and a Spall Supermarket on the next corner for any essential's. My third stay in Can Pastilla, not my last for sure.
