My wife and I, along with our one y/o, stayed with MJ for a week when we visited LA for the first time for a close family wedding. MJ was a great host. MJ was very quick to respond, had answers to all of our questions, and was very accomodating.
The pictures of the space don't do it justice as to how much room you have. The space was bigger than we expected, we were able to fit a crib into the bedroom with room to spare, and the bathroom was very nice and spacious. It was nice to have the privacy of the backyard and getting in and out of the property was very easy.
The neighborhood is very nice and completely walkable. There are nice bars, restaurants, bakeries, and coffee shops within easy walking distance. It was also easy and safe for us to walk to many attractions further away in the area (even with a stroller). Having never been to the city this was important to us and we were very happy with our experience in this regard.
MJ's place was also very clean. This was very important to us with a kid crawling all around and we were immediately at ease when we entered the space as we saw how clean the place was. We would definitely stay here again.
