Updated, clean and roomy 1-bedroom in an astonishingly good location. Literally next door to Belmont Station (more about that in a minute). Restaurants, stores, and Wrigley all nearby. Your window looks out onto the Belmont train platform, which might be a little disconcerting, but there is absolutely no train noise, as other reviewers have also noted. Hanzel and Reese are thoughtful hosts, quick to reply to questions or needs.
Pro tip: Spothero rents spaces in a lot in an alley just across the street for an economical price.
