Shahab is a great host. He is very flexible with everything. Be it check in time and what time you come in and go out ( Can't comment about check out as I left on time ). But I was in need of early check in and Shahab was quiet welcoming. He will make you feel as it is your own home and you can come at whatever time you would wish to at home. House is super clean and area is quiet. It takes around 30-35 minutes to reach city center. You have good connectivity. But make sure you follow public transport timings closely as if you miss one, frequency I found was every 10-15 mins. I couldn't meet personally Shahab but you can approach him anytime over call and he responds well on time with whatever you need from him. Very friendly I must say.
I would recommend his place if you are visiting Edinburgh. Thanks Shahab.
