The only mistake made on this stay was that I hadn't booked for longer!
Initially, it was very easy to reach the guest house via train and was very easy to find when walking from the train station. Not being far from an Overground station, it has very good connections to the Underground and National Rail.
The check-in process was quick and simple. The member of staff who greeted me was very friendly and guided me to help me find my way around.
The room itself was spacious and clean. It's not geared up for business/working but the furniture in the room was more than enough to do what I wanted it to. The bathroom was also very spacious and the shower was amazing!
One, perhaps obscure, feature of the room I loved was that there was a fan already in there (I didn't need to ask) and it was floor-standing (so I didn't have to wrestle for a spot on a table for it). This meant I felt very comfortable for what felt like a stuffy night (not the hotel's fault).
The check-out process was very easy as well. The members of staff were very friendly and were more than accommodating allowing me to use a table as a workspace until my train arrived. This, of course, meant that I ordered some lunch which was very good quality.
I will absolutely consider The Royal Oak for my return visits to London.
