We really enjoyed our stay in Johnnie's apartment! It's in a fantastic location, clean and cosy and Johnnie was very friendly and helpful when we met him. Communication was top-notch too.
The code system is great for getting into the building/room (not worries about losing keys!) and Johnnie supplied a lot of things in the apartment (soaps, milk, tea, cereals, even wine!).
One slight issue was the room is very bright in the morning if it's sunny! If you're a light sleeper, you may want to bring an eye mask.
