Melvin's apartment is indeed a good value, but keep in mind that you get what you pay for. You won't be staying in someone's home, but instead in an apartment that makes up a block of rooms rented out to tourists. We didn't even get to meet Melvin, but instead one of his business associates. So it wasn't the warmest welcome, but it was efficient and business-like.
The apartment is very clean, though it is a bit small (especially the shower). We also had an issue where the electricity went out over night and we were unable to get it fixed before we checked out in the morning. This was a little inconvenient and it would have been nice if the host had made it a priority to get it fixed as soon as possible.
