Free Starbucks coffee. Need I say more?
Alberto was by far one of the easiest hosts I've dealt with. He sent clear directions, left printed copies on the desk complete with WIFI instructions (why don't more hosts do this?!), and completely trusted us with his place. The bed is very comfortable; the room well-equipped (though a little tight). The entire apartment was very clean. I'll likely stay here again.
Note: If you're a light sleeper, don't open the windows -- there was a dog nearby barking until after dark and the A/C unit outside the back window makes a horrendous scrape as it kicks in. I stayed two nights and did not notice any of this the first night with the windows closed, but that first night was 32 degrees outside and the second was up in the 60s (Ohio temperatures can fluctuate like that sometimes) so the room was warmer, meriting the open windows.
