My bathroom lizard

I thought at first that my jet lagged eyes were playing tricks on me... i kept seeing moving shadows... and then I eventually realized there were lizards in the villa. This little guy is the smallest of the bunch, maybe 5cms long? I don’t mind these little critters. In fact, they rather intrigue me. This guy has been hanging around either in the bathroom or the bedroom and I told him he can stay so long as he eats up all the bugs, especially the mosquitoes!
