Hotels in HanoiA simple Old Quarter hotel with spa services, not a full-service four-star
6.6/10
Excellent location and helpful staff, but room upkeep makes this a cautious pick.
Silk Castle is a simple Old Quarter hotel with spa services rather than a convincing full-service four-star. Its strongest argument is location: Hoan Kiem Lake, the night market and plenty of places to eat are close by. Booking.com and Expedia guests repeatedly praise helpful staff, and breakfast earns positive mentions. We'd consider it for a short, location-first stay, but wouldn't choose it for comfort alone.
Room quality is the sticking point. Alongside satisfied guests, recent Booking.com, Expedia and Tripadvisor reviews describe cramped rooms, uneven cleaning, damp or drain smells, and bathroom maintenance problems; some Tripadvisor guests also report unreliable hot water. Some rooms lack windows, while street-facing rooms can be noisy. These recurring complaints make it a mixed proposition despite generally good ratings on the larger booking sites. We'd skip it for a quiet break or dependable four-star standards.

Best for: location-first Old Quarter sightseeing; short stays with modest expectations
Watch out for: small rooms, some without windows; uneven cleaning and bathroom upkeep; street noise and damp smells
Location: Excellent walking base near Hoan Kiem Lake, the water puppet theatre and night market.
Rooms: Compact and variable; confirm an exterior window rather than assuming one.
Cleanliness: Many guests are satisfied, but recent reports of stains, dirt and damp recur across sites.
Service: Helpful staff are a consistent strength, though problem handling receives some criticism.
Amenities: Breakfast, elevator, Wi-Fi and spa treatments are listed; expect a simple city-hotel setup.
Fees and surprises: Airport transfers cost extra; no onsite parking, and cancellation terms depend on the booking.
