Casa del Rai was a great place to stay! It was our first time in San Pedro and Alex - the manager, Aileen and her husband - owners, were all very accommodating and helpful with things to do around town.
The room was just as described. Very nicely decorated, clean, roomy, no issues with the A/C, they had plenty of towels and a fully stocked kitchen for us. We didn't cook much during our stay, but it was nice to have all we might need. They even had some drinks and Belikin beer in the refrigerator; a very nice touch :)
The place is within walkable distance to the restaurants and nightlife, but I'd recommend a golf cart for getting around. Alex helped us find a great deal on one at the hardware store literally across the street from them. We rented one for a couple of days and it was nice to get around and explore. Alex was very helpful with recommendations and quick to respond with any questions we had about getting acclimated to the room.
My only tip would be if you're a light sleeper, bring ear plugs. There's a lot of construction, traffic, roosters and dogs around. Overall, I'd highly recommend Casa del Rai and would stay there again!
