100% recommended! When we are in LA next time we would be definitely happy to stay at Dario's place.
As to the details, we're a couple in early 30s from Europe. The place is very clean in a very good condition. Besides that Dario and his family thought about each detail guests might need during their stay and made all effort to make it as smooth as possible (well equipped kitchen, towels, shampoo/cosmetics, coffee/tea, local guide books, high speed internet, no problem parking, even cable TV (we didn't switch it on). Very prompt and clear communication. Well though and smooth check in. 100% privacy in a separate small guest house, but
if you need any help big advantage that Dario is available to help close by.
The location seemed safe and it is definitely quiet. If you come by car it's very close to a freeway (big advantage, no worries you can't hear it). Of course you have traffic, but that are not specifics of NoHo but LA in general. Tourist attractions in Hollywood are very close by car.
To sum up if you don't like hotels that much and prefer to experience the city more as locals with much higher level of comfort in my view, this is a place for you
