Jonny's place was such an amazing find for me and my family as first timers in London. There was 4 of us in total (all with large suitcases) and there was so much room in the place that we didn't feel cramped at all.
The first thing I noticed about Jonny's flat, was the scent of cleanliness; and that was definitely reflective in the whole flat, from top to bottom! Having two bathrooms was probably the best thing ever as there were four of us!
Jonny is a very responsive host, and was able to help me out right away when I locked us out of the flat one morning.
The only thing that was bothersome for us, was trying to get all of our luggage up the stairs (as there is no elevator) and the stairwell was extremely narrow making it difficult to carry our luggage up & down.
Location wise, his flat is between two larger stations making it easy to get to and from different places within London! There are plenty of grocery stores, coffee shops and eateries around the area as well.
With all that being said, there were definitely no regrets for booking Jonny's flat at all and I would recommend it to everyone travelling to London!
