The Gem was the perfect place for my wife, pup and me to stay while we were looking for a house of our own in the area. Communication with the hosts was perfect from the beginning. Michael even asked our preferences for the breakfast items he left us for our first morning there (such a nice touch!) and quickly let us know when we left a few items behind and figured out how to get them to us.
We stayed for a month and loved everything about it. The location is awesome, you can walk to coffee shops, restaurants, bars, yoga, spas/salons, grocery stores, etc. on Piedmont Ave and Broadway (and beyond if you want to walk a little further), Macarthur BART is a nice 15 minute walk (which we did several times to go into the city), and the neighborhood is nice to stroll around (we took our dog on several walks per day). There is also free parking on the road that the house is on if you have a car with you, but pay attention to the street sweeping days!
The space is relatively small but was great for the two of us and our dog, plenty of room to move around and does not feel cramped at all. It was well-equipped with everything we needed during our stay, including the kitchen, which had exactly what we needed to cook a few nice meals. The back porch and yard were so nice, the weather was perfect to spend time out on the balcony and our pup absolutely loved playing in the backyard.
Overall, an awesome stay and I would not hesitate to recommend this place to friends/family in the future.
