“In my opinion, while it aims for digital convenience, the experience seems to fall short on basic comforts. Reports of cleanliness and maintenance issues raise concerns about the actual guest experience. Its distance from the city center further complicates what should be a simple stay; I think that travelers might find better value closer to town.”
