Be prepared to speak some basic Spanish in order to get along. Quito is an excellent city in which to learn Spanish before heading off to other places in South America. The Spanish spoken in Quito is very clear and it is spoken slowly as compared to coastal areas. There are many excellent Spanish schools where you can have private or group lessons very economically. These schools will also arrange homestay accommodation which is convenient, inexpensive and a wonderful way to immerse yourself in the culture and try the local food.
Very few locals speak English except in the touristy areas of North Quito which includes "La Mariscal" quarter, where most tourist businesses are located. La Mariscal occupies several square blocks in North Quito and is the place to be if you wear a backpack. Bars, restaurants, hostels and internet cafes abound. Young people from many countries tend to congregate there.
Ecuador, especially the Sierra region that includes Quito, is culturally a very conservative society. This is reflected in manner of dress. People of all socio-economic backgrounds tend to dress up in Ecuador. For men, this means a pair of trousers and a button down shirt. For women, slacks or dresses are acceptable. Men and women seldom wear short pants in Quito, although in recent years casual clothes have become somewhat more accepted especially among the young and on very hot days. Some popular nightclubs and restaurants enforce a dress code. Lastly, remember that Quito is said to have "all four seasons in a day". Once the sun goes down it can get downright cold. Dressing in layers is a good idea.
