I would thoroughly recommend if staying in Istanbul.
The apartment is close to Galata tower and a 30-45 minute walk to all major tourist sites across the river. Public transport is also close by if you wish.
I was working remotely during my stay and all facilities exceeded my expectations. The host was also extremely responsive when speaking with him. However the detailed guide provided more than covers everything you'll need during a stay.
I would love to stay again on future visits to Istanbul.
