Transport in London is quite expensive. A single trip on the underground will cost you near 7 pounds. That is why what I recommend is to get an Oyster Card. It will cost you 5 pounds in deposit ( fully refundable when you return your card). Then you load it with 7 pounds and it will give you an unlimited number of trips on London Underground, buses and trains within central London. You might also consider taking a black cab from time to time. An average trip by black cab in central London will cost you 15-20 pounds. And if you just want to get from a to b it will be cheaper than the underground.
Anyway , if you have questions please do not hesitate to contact me 😉 #transport #london #oystercard #cheap
