Cosmo Hotel Mongkok
Despite not being in the center of Nathan Road, rather off the beaten track, it is perfect for a few nights in HK. The hotel is relatively new, the decor is modern and the rooms are well equipped, even with adapter plugs. Obviously for this price the rooms are very small. Just enough for beds and a small glass cabinet above the minibar. Opposite there is a McDonald that is open 24h and plenty of restaurants and shops. It is located near Olympic station, which offers a short ride to the center of Kowloon. It has free wifi in the lobby and reception area.
