W's place is conveniently located in Ximen where it's very practical for shopping, food and nightlife. There's someone at the downstairs front desk at all times, so it feels pretty safe, and W was very nice and made arrangements to meet us and show us the basics of the apartment. I ended up sleeping downstairs on the futon, while the other 3 girls in my party had the 2 beds upstairs. It was a little tight for the 4 of us space wise, but we managed fine. There's a small fridge for storing a few snacks, and a washer and dryer next to the elevators. Separating the trash was a little confusing for us, so it was nice when the person working in the basement (where you have to take your trash) just took it from us right off the elevator.
It is a short walk (about 2 1/2 blocks) from the train stop. Exit 1 (Red House) is the closest but didn't have an elevator or escalator, so it's more practical to use Exit 6 when you have luggage. It's also nice after sightseeing in other places, to arrive back in Ximen just to walk around in the evening to do a little shopping and grab some street food. There's also a Starbucks at the corner, and an Olympia bakery around the corner to grab some breakfast and coffee in the mornings. Overall this is a pretty cute, clean and convenient location for sightseeing.
