It is one of the most popular hostels in London because the prices are good and it has what is perhaps the cheapest bar in town. It is a mega hostel with 800 beds with a starting price of 15 pounds (18 €) which includes a buffet breakfast. They make their money mainly from the pub / restaurant, where your can have breakfast, lunch, and dinner a la carte. It's pretty loud, so I'd suggest using ear plugs for those who are not very nocturnal.
The best place to stay in London, at least in my experience! It's completely different from anything else, set in a former prison. You can still sleep in the old cells if you want (a chilling experience, but I don't recommend it: they are cold and narrow, and anyone can spy on you through the peephole). The breakfast is generous, and there is a large kitchen for you to use. Parties are organized frequently in the bar, and there are also vending machines. The staff are friendly, and the atmosphere is young and dynamic. I recommend it!
One of the most recognized and busiest hostels in London. Very close by, just two minutes away, is the King's Cross Station and the Eurostar train. A few minutes walk you will find the legendary famous Camden market. Of course, if your budget is tight and your intention is to see all of London, Journeys Kings Cross St. Pancras is one of the best options. Their team will be at your disposal to answer all of your questions about the city. It has all the typical services of this type of accommodation: 24 hours access, laundry, wi-fi, breakfast and linens included.
I went to the Hostel 639 in June 2014 for 4 nights and had a great experience. Breakfast costs less than £2 and is unlimited (grilled bread, butter, jam, spreads, cornflakes, coffee, tea, milk, everything you like!). We booked beds in a mixed dorm for 8 and they ended up giving us a private room for four with its own bathroom. What an amazing surprise!
It's pretty basic and I would not recommend it as hostel for first-timers, but it's perfect for experiences backpackers and very clean (including the sheets and rental towels). We even managed to find different people to go out with at night! There's a tube station right in front of the hostel (Kensal Green, open until midnight ) and a bus stop about 100 meters away. There are two public rooms (which I didn't really experience much), one with a bar and another with sofas and a TV.
Small hotel but with a very good quality/price ratio. The rooms have a sink but the shower and toilet are shared and cleaned very often, each guest has an individual locker in the room. There is free wifi throughout the hotel and breakfast is included in the price (toast, croissants, cereals, muesli, butter, jam, orange juice, apple juice, milk, coffee, chocolate and tea). All day there is free water and it has a TV, bar, pool table and indoor and outdoor dining. Totally recommended.
Palmers Lodge Swiss Cottage is a 2-star hotel ideal for those who enjoy traveling but don't want to spend to much money. It's not a luxury hotel but it's extremely clean and the bathrooms were cleaned and disinfected several times per day. The common areas were all nice and heated. Overall, I'd highly recommend it.
A less-expensive way to stay in London is to opt for a youth hostel. We've stayed at St. Pancras various time. Don't let the "youth" label discourage you, there are travelers of all ages! For me it has several advantages:
1-While not cheap compared to hostels in other European countries, it is cheaper than a hotel yet still has many amenities.
2 - Includes a very hearty breakfast.
3 - There are rooms of various sizes, with or without bathroom included. If you opt for the shared bathroom, the price drops. The rooms are simple and have bunk beds but they're alright if you just want to get some rest before exploring the city.
4 - They dinners are more affordable than what you'll find on the street. The only downside: the schedule.
5 - There is a kitchen with a refrigerator available to customers, as well as dining table, washing machine, and lockers.
6 - The location is perfect, literally next to the King's Cross - St. Pancras tube stop. Lots of bus lines also pass right in front of the hotel.
8 - Finally, you can stay up to 11 nights, whereas most youth hostels limit stays to four or five days
