Simon's place was great for a 3 night stay--big apartment with lots of space and (seemingly) newly-renovated bathroom. Lots of restaurants and food options nearby, as well, and walking distance to Columbia. Overall I had a really great stay and Simon was extremely communicative.
Only con of note is the floor radiator in the bedroom is frustratingly loud when it clicks as it's turning on and/or heating up. If you're a light sleeper like me it can be enough to wake you in the middle of the night (and not having control over the heat was a little frustrating too as I prefer to be cold when sleeping). I understand there's not much to do about the noise of the radiator, but just be aware of this if visiting in the winter months (and bring ear plugs or something)!
