This is a truly lovely apartment and très chic!
It's a loft with an upper level for sleeping and a bathroom. Everything is very thoughtfully decorated and very clean. There are many, many plants that make staying there an even more comfortable experience.
The patio that is attached to the downstairs section makes the place feel even more spacious than it already is. The apartment has everything needed and beyond for a long-term stay (I stayed one month at Erik's place).
Even though the street in which the building is located is maybe not SF's nicest, the location is very central and everything is easily walkable (Valencia Street is right around the corner). There are plenty of restaurants, cafés, and stores within just minutes walking distance.
I would always love to return to Erik's place!
