Melissa is a lovely person, even if we didn't actually meet. We mentioned that we're vegans and she left a list of places we could eat at, and that was really useful so thanks for that! Her bedroom (which is the one we ended up staying in, even if at first we weren't meant to - but that's not her fault and it was absolutely not an issue) is cozy, the bed is quite hard (it's a futon) so that could be a problem for some people. It's right next to the kitchen and the backyard area, so it can get a bit noisy at times - it never really bothered us though.
The house is old but they keep it tidy, though it's really quite dusty, especially on the edge of wall tiles.
Other than the toaster, we didn't use the kitchen so we can't say anything about it.
All in all, we would recommend Melissa's place.
