This is a cute little apartment that used to be a salon and is a side addition to D's Hostel but separate from hostel rooms, off to the side. It fit our needs well. Rafael, Dorita's husband, was such a great host and helped us out with tours cheaper than the going price and recommended how to see the Xunantunich ruins without having to do an expensive tour. When the city shut off the water to repair old pipes, he was a great help in getting us buckets of water for use. He also lent us water shoes for our ATM tour since we lost ours and couldn't find a store to get a pair. Though we ended up buying other shoes that actually fit (at the advice of the guide) at a pitstop right before the caves, we really appreciated the plan B. Whenever we had questions or issues, they were prompt in help and reply.
Location-wise, it's right at one end of Burns St right across from Guav Limb Restaurant and a short 3 min walk to the hub of San Ignacio. We walked to Cahal Pech ruins (BZ$ 10) which took at 20-25mins but much faster coming back as we didn't have to look for directions. Very near a lot of tour company offices and if they do pick up, they know where D's hostel is. Xunantunich is just a short 15 min local bus ride away (for BZ $2) - just need to tell the bus conductor (money collector)/driver you want to get off at the Xunantunich ferry crossing, cross the river (free) and walk about a mile up to the ruins (entrance fee is BZ $10) - lots of mosquitoes, bring repellent.
If you're a light sleeper, note that music can be heard from various bars/restaurants at D's since it's so near where all the activity is. It's not very loud as D's is at one end of Burns St; kind of like upbeat music in the background. My sister is a somewhat light sleeper and didn't have problems.
To get to D's from Belize City, you can take the local bus to Benque and get off at San Ignacio for BZ$ 10 at the square/park right in from of the visitor center. From there make your way to Guava Limb (3-5min walk) and D's is on the other side of the street.
We would stay here again.
