My stay at the hotel was a mix of positives and negatives. The location was excellent, right in the center off Union Square, making it convenient for shopping, sightseeing, and transportation. The rooms, however, had odd furnishings like a chair with a large hole in the upholstery, which was a bit disappointing. The staff were cheerful and helpful, adding to the pleasant experience overall.

I found the hotel to be a mixed experience. The rooms were clean but had some issues like a persistent smell and lack of amenities. The service was friendly but seemed overly focused on tips. The location was great for exploring the city but had some safety concerns. The dining options were varied but pricey compared to alternatives outside.

The rooms had a persistent smell that required keeping the window open. They were only cleaned every 3 days and lacked basic amenities like a refrigerator and a working phone. Some maintenance issues were present like a faulty safe and a non-working phone.

My stay at the hotel was truly enjoyable. The room, though not as spacious as advertised, was clean, modern, and refreshed, with a convenient high top table for work. The service was outstanding, from the valet to housekeeping. The location near Union Square was brilliant, just a block away, and the dining options were good despite being a bit noisy. Overall, a great stay with excellent value for the price.
