3. Specify your requirements such as parking, internet, price range (I normally, set the parking and internet requirements first, then set requirement for "stars" and then select the cheapest option within category)
4.Then choose an option to show the map
5. Book the best hotel according to reviews which is near the city center or have good public transport access
Pay attention to:
Cancellation conditions (e.g. in what time period you can cancel reservation for free).
Parking (sometimes they write that there is a parking, but it is not hotel's parking, so you'll need to walk, sometimes it can be 5 minutes walk, so choose hotels with private parking if possible)
Breakfast (if I don't have tough schedule, I'd prefer go out in the morning and take a breakfast in the city center, for sure this works if your hotel is in the center and you leave about 9-10 a.m.)
