Personally, I wouldn't totally disagree, but it is very much in the eyes of the beholder what "nice place to live" means.Based on your post, I would assume you are getting requests because you are a new landlord (maybe the old one was not a kind person, so tenants chose not to make any requests) and that you are asking them to pay more rent for a unit that is likely in worse condition than when they moved in.So now, you can either tell them no, or you can accommodate and potentially open up pandoras box of setting expectations that you will cater to all requests all the time, or as noted, you can remove yourself from the equation and hire a PM to handle the requests.
