Kevin's place is great - the best part about it is the location. I really enjoyed Bywater. It doesn't feel tourist-y at all and there's a ton to see and do close by. The apartment itself is cool. It's got a lot of nice touches - tons of books on the history of the area, photography, etc. There's lots to look through and it makes the space really interesting.
I will say that the bed is quite hard so if you're not into a firm mattress, you might want to look into this. Also, there's quite a few mosquitoes so just remember to pack some bug spray (although Kevin provided us with a bottle, so you could be all set).
