Location, location, location.
We were in for the BST Festival at Hyde Park. This was near by, and within 15 minutes walking to get to where we needed to be at the park. Etsh was an amazingly responsive host, and really made the check in and out very easy. I would absolutely consider his place again, if my journey returned me to London. A few small markets across the street were helpful, and tube stops were within 10 minutes walking. The accommodations were as described. If you’re from the US, the bed is a double. All items worked as needed.
