This is an utterly ideal spot for one person!
Pros
Parking: super easy and plentiful street parking. Unlike in neighboring Pasadena, you can park on the street overnight without a permit, and since it is a fully residential area with driveways and garages, there was always ample street parking right outside the house
Privacy: with its own side gate entrance, I felt fully private in this little studio, despite its proximity to the main house. It was also perfectly quiet and peaceful - ideal for working during the day and sleeping at night.
Location: I am a big fan of the plentiful and varied Asian cuisine in the San Gabriel Valley, and this place is smack dab in the middle of some of my favorite spots (Golden Deli, Golden Delight, DX Labs - just to name a few). It is also less than 10 minutes from the Huntington, less than 20 minutes from downtown Pasadena, and less than 15 minutes from the Arboretum - all places I visited during my stay.
Cleanliness - as advertised this place is absolutely, sparkling clean! Since it looks like a newer build, everything is fresh and clean and well maintained.
Comfort - while small, you have everything you could need for your stay - a comfortable bed, A/C and heating that works efficiently in the small space, a spacious shower, a very functional little kitchenette, a nice big table that can double as a desk, and a good amount of storage for your things.
I definitely recommend this to anyone looking for a clean, comfortable, private, and convenient stay in the SGV!
