Disclaimer - My friends and I don't have high standards, we're fresh out of college, and typically stay in dormitory hostels when we travel as a group.
Cons: Filthy - as soon as we got there, the toilet was clogged, the sheets were dirty, and the counters were smudged and dusty. Worst of all, the bugs everywhere (bathroom and kitchen).
Pros: Location, and the host is very easy to contact and quick to reply.
To summarize: It would really be a 5 star place if the place was maintained and actually cleaned by the host (amidst all this there was a cleaning fee?).
