We stayed at the Travelodge Finsbury Park from Oct 31 to Nov 6 2019. The hotel is no-frills, but it's affordable & clean and the staff is very friendly and incredibly helpful (and let's be honest, you don't visit London to sit in your hotel room). You're only a short walk to Emirates Stadium and to the Underground, and there are numerous pubs and restaurants within walking distance as well. I will absolutely stay here again.

Stopped here for a night as we were attending a wedding in London.
This is a typical Travelodge in that you know what you are getting.
The hotel was clean, the staff were friendly and the location is very good in regards to local food places and access to tube stations.
My only issue is the lack of parking on site.
I understand it's London and space is limited, but if you want to park you have to leave your car in a local car park near by.
This is despite (I believe) the website saying they have a car park.
