We stayed in MJ's place for three weeks and this review is for the "front" half of the duplex (the one-bedroom unit with the kitchen and washer/dryer) -
do note that some of the reviews may be for the other unit (or for the whole house).
MJ's place was a great find. We were looking for place that was centrally located but was still private, that had ample space for two people to work remotely while on meetings, and had an outdoor space for us to use. There was more than plenty of space indoors, and we had access to both the front and side yards which was really great! (Do note that the side yard is private and enclosed, but the other unit's entrance and path does go through it). It was also very conveniently located (easy to get to major freeways, off of the main streets so it's pretty quiet for being in the city, lots of surprisingly excellent food within walking distance), and street parking was generally very easy and convenient. MJ was extremely responsive as a host even at late hours, and he was very willing to help make sure we were comfortable in his space.
There were a few things we thought could have been better: the lighting in the apartment was quite dim a night and we prefer having bright lighting; we were hoping the interior would feel more modern and the space and furniture were a little bit on the older/heavier side; the bathroom was a bit small and felt a bit cramped; and there was a small problem with the thermostat tempreature reading that left us a bit on the chilly side (to MJ's credit, this issue was resolved about halfway into our stay after a bit of troubleshooting).
All in all, MJ's place has a lot of great things going for it that are really hard to find in the area. If you're not as picky about downsides we experienced, you'll enjoy the space!
