Very very friendly and helpful manager, who helped me buy more data for my phone, gave me directions and advice on which bus to get to Yazd, even after I checked out and was at the bus stop, he was still available for me to ask advice on the buses, which was really helpful, as I'd have gotten one of the lesser quality buses had he not been there to help.
The hostel was very nice and clean, with beautiful fluffy blankets, and perfectly clean bathrooms (very important). The distance isn't too far from the main attractions, but if you're there in the summer as I was, it can be a bit far to walk in the heat.
This isn't a problem though, as you can order a ride into the main part of town on the snapp app for only €0.45 or so.
I'm already planning my next trip back to this beautiful country, and Pava Hostel will without a doubt be where I'm staying next time I'm in Isfahan.
