Joshua is a very responsive host. The place is great overall. Very roomy. The receptionists are pretty helpful too.
It's fairly close to taksim alas with a few minutes of climbing on the way. There are little grocery stores right down stairs and a cute coffee shop as you walk up toward the main street.
If you're with a big group, Joshua's place is definitely worth it. He's also very flexible and helpful if you need anything. we had a great time there.
