This is the largest Home Exchange platform in the world. We used it and exchanged our apartment with a family from Paris and had an amazing two week long vacation. We highly recommend to check and to use this platform.
1) Momondo - Compare prices (Hotels, Flights, Car rental)
Momondo offers not just to find the hotels, but here you can see the lowest price available because it detects and compares prices from all major hotel online booking platforms. The system allows tracking costs for exact search. For example, if you are looking for a particular amount of hotels in a precise location, just set a price alert and they will send you an email if there is a notable change in rate. Moreover, Momondo offers many options to filter search (guest rating, price, location radius from the exact place, etc.). Also in the same area, you can find cheap flights and rent a car.
Booking.com provides an opportunity to find cheap hotels, hostels, and apartments. We like that booking.com allow using Map Widget. If you like to find accommodation in some exact place which exists on this website, below each location, you can see a map with hotels around the site. It is beneficial if you do not want to waste time going from one place to another.
No1 in Asia, offeres competetive prices. Possible to select location on the map.
