- Restaurang Sumlen, in the basement of Kungliga Biblioteket (the Royal Library) in the Humlegården park (T Östermalmstorg) . Open M-F 9:30AM-4PM. In an area where sit-down lunches are expensive, Sumlen, catering to poor PhD students, offer simple but decent meals for 58SEK. Closed in July.

Blå porten, hidden in the back yard of Liljevalchs konsthall, is the one exception. Delicious food in a lush garden makes the long queues worth it. The excellent cakes and pies also makes this a good choice for a coffee break.

- Brasserie Godot, Grev Turegatan 36 (T Östermalmstorg) . If you fancy long drinks with a cool crowd this is the place for you. Ask for an Old-Fashioned, Godot Crush or a Bloody Mary.
- Backpacker's Inn, Banérgatan 56 (T Karlaplan), (email@example.com), . Actually a school, more or less converted into a youth hostel in summer. It is large (320 beds) and really centrally located, close to the subway (200m), and within walking distance to downtown. There is a shopping mall and several supermarkets nearby. The showers are in a separate building (since the only ones available are those at the gym hall), and the sleeping rooms (14 beds) are classrooms. Breakfast (decently priced) and internet (expensive, go to an internet cafe instead!) are available. If you need a cheap place to stay and want to meet a lot of people, this is for you. 135SEK in the dorm for STF members  and 180SEK for non-members. However, one should be careful about his luggage, as recently a student from India was a victim of laptop and mobile theft.
- Hotel Stureplan, Birger Jarlsgatan 24, (T Östermalmstorg) . Central, therefore relatively pricey at around 1000SEK per night. Comfortable, well designed rooms and the location is ideal for shopping and sight-seeing. There are "classic" rooms kitted out in 19th century style, and minimalist "loft" and "cabin" rooms.

The breakfast buffet conveniently lasts until 2PM, perfect for those wanting to sleep in, and is generous and excellent, making it a great start to the day. Guests are able to rent bikes from reception, and considering its ideal location, its a great way to explore the city at your leisure.
