Elien's apartment is as beautiful as the photos - with great light, books, and decorations. It's two blocks away from the G, and has cute coffee shops and restaurants a couple blocks away. The apartment is spacious, with high ceilings (industrial look) and large windows.
A couple things to keep in mind before booking:
Temperature is hard to control, as it seems the entire building has heat pumping through it the entire day (vents in the apartment are mostly taped off). However, there is an AC unit in one of the windows that can circulate through the entire apt. There is a lack of hand soap and other specific cleaning agents, so if you are particular about that - bring your own. This listing is booked out very often, so I'm not confident that everything (bedsheets, towels, etc) are properly washed between stays as they smelled a bit used.
In all these things wouldn't prevent me from booking again, but I would be more prepared next time because I am very particular about such things.
