I travelled to London with my elderly parents with arthritis- so having a lift and a walk in shower rather than bath-tub was brilliant. The house felt like home- we stayed for 10 days and did not feel like leaving. It was warm, cozy, beds were comfortable. We cooked a bit (but missed a baking tray) and loved the feeling of home. We used every space- spread out all our stuff- there plenty of closet space, so you don't need to live out of a suitcase. They had chargers, adaptors, good wifi. It was a haven of peace and calm.
To go to the main road though the road in front (High timber is closed to traffic) so you need to climb the stairs to Fye foot lane- which was a bother for people with knee issues. The better route to go to the bridge was to use the Thames access path and an escalator to St. Pauls. Besides that the location was wonderful. You can walk to St. Pauls in 5 minutes! We really had the most brilliant time!
