I've stayed at Casa Bella twice: July 2024, & January 2025!
If you have tempered expectations as a solo traveler on a budget, it's adequate accommodations. You have wifi, a TV, a bed, & a sink in your room. I was fortunate to have the shared bathroom across from my room! It's also located a block away from Place des Arts & its métro stop, across the street from a Provigo supermarket, Couche Tard corner store, an A&W down the street, & a nice brunch establishment named Cafe St Barth's a couple of blocks away!
While I was satisfied with the A/C during the summer, I was less than impressed with the lack of heating. It was barely adequate with my warm clothes that I happened to pack with me, but crossing the hallway to the bathroom, it was cold! I would ask that they increase their heating to facilitate the guests' comfort!
