PROS: location location location. I was able to walk to basically everything I wanted to and after a week or so I was starting to feel like a local.
The host. Silvia was exceptionally communicative, welcoming, and ready to help from the very beginning.
in addition the place is clean and comfortable for one or two people.
CONS: none as long as you read the description. The only "negatives" (hot water, street noise) are the ones clearly mentioned in the description. It's not luxurious; you know you don't get luxurious for 30 bucks a night. Where I'm from you can't even get a couch to crash on for that kind of money...
also wanted to mention--not saying the previous reviewer didn't see what she saw, but for what it's worth in five days I never saw one single bug of any kind.
To sum up, it was a good experience, with a great host, well worth the money, and I'd definitely stay here again.
