London Hotel near Euston

Premier Inn Euston or Premier Inn St Pancras. Both within a 5 min walk of Euston station.

Premier Inn is a good call, the HoHo bus not so much unless you like sitting in traffic. They are not a form of transport. Use ordinary buses or the Tube, Overground, Elizabeth Line.

Thank you for the referral to Premier hotels. I will check them out. They seem popular.
To be clear, we are using HOHO bus for touring only, not for transportation.

I still wouldn’t. You will mostly touring traffic jams. They aren’t allowed to use bus lanes. A total waste of your time and money.

As long as you understand that traffic in London is terrible, then take the HOHO bus if you want to.

But don't use it for on and off privileges. It will take too long to get to a sight and then wait for another bus. My suggestion is to use it as an overview tour then utilize public transit--tube, bus, whatever--to actually travel between the places you want to visit.

Thanks so much for the further info on the HOHO bus tours. Did not realize they cannot use bus lanes and we certainly don't want to sit in traffic all day. We will rethink our plans. Love this forum !!
