We stayed at the Peridot twice during our time in Vietnam. For both stays the hotel was great. Lovely friendly staff, very clean, nice facilities and a big comfortable bed. The breakfast was excellent too. The location is ideal, close to lots of eating options. We walked to most of the sites from the hotel with ease. Cabs are plentiful and a good price if you don’t want to walk. The Grab app works really well in Hanoi. We also used the hotels airport transfer service (4 times), which was obviously more expensive than a cab, but still priced very reasonably and an excellent service. We wouldn’t hesitate to recommend the Peridot for anyone staying in Hanoi.
