Quick summary: For the "average/normal" traveler/visitor, this place will probably be a great value and option. For special/sensitive needs beyond the "average/normal" traveler/visitor, I would suggest communicating with Marcus in advance to make sure it'll work for you.
I looked through the year's worth of reviews left before my stay. I would say I could understand how they were all true for those guests. The best part about our experience was Marcus' communication and responsiveness...we definitely felt like he had our back and would do what was appropriate to make things work and make things right. The worst parts about our experience was probably the wifi being inconsistent/unreliable as well as the kitchen/dining amenities and laptop workspace situation being less than other comparable places where I've stayed. One improvement/remedy could be a folding card table. For most people, these may not be significant issues. For those looking to do some food storage/prep/cooking/consumption (especially with more sustainable options than disposable flatware) or desk work, it may be wise to check with Marcus in advance.
Otherwise, lots of great things about this place and host! I would definitely stay with Marcus and at this property again! Enjoy!
