Arrived in Taganga intent on staying on the beach because there's quite a few of hostals along the beach. We priced a few, and they all seemed quite average but on a very outdated Lonely Planet recommendation we went to Casa Blanca. The girl in reception had great English and initially quoted us CP60,000 a night! That was DOUBLE what the LP said and what other hostels were charging but it was because "they didn't have a lot of rooms available" she said. When we laughed it off and left the premises she came running after us & said a room had just become available & she could let us have it for CP35,000! We were a bit miffed but keen to stay there as the location is great, so we looked at the room which had its own bathroom and decided we were happy with it.
The hostel kitchen was disgusting - we attempted to cook here once, but found it near impossible as it's very poorly equipped - broken saucepans, frying pans with no handles (!?), very few utensils, and when you spotted something you might be able to use, it was usually dirty & lying in dirty dish water. There were also ants crawling around and tons of flies. We kept some ham and cheese in the fridge so that we could at least make sandwiches for the beach & our food went missing, even though it had been labelled. We complained and reception seemed pretty blasé about it, it was only when we got really angry and threatened to leave that they offered to replace the items.
The room itself was a bit grubby and run down looking, much like the rest of the hostel. Some of the rooms have hammocks outside on their balconies and sea-views. Our hammock contained an old tube of toothpaste, which was interesting!
I'd recommend this hostel if you're on a tight budget & staying with friends in a shared dorm room as you would probably be able to bargain them down quite a bit. It's right at the end of the beach, so it's really quiet at night which is great when you fancy some sleep and it's wonderful to wake up to the sound of the waves in the morning and quite literally step onto the beach.
There's a little restaurant next to the hostal too, we ate there once but found it quite pricey for what we got.
