If you are in the city center near Parque Calderon and you need to make a phone call or use the internet then MaxNet is the closest reliable cabina; it is on Benigno Malo close to Presidente Cordova. They are almost always open, even on some holidays. They never try to get more money out of you; their prices are listed on the window. Sometimes the last phone booth doesn’t have the best connection but I’ve found that the MaxNet phones have a better connection than most places. You can make color copies here too but if you need to make a ton of copies then head over to the printers sector of the city which is around Tarqui y Gaspar Sangurima.
In this neighborhood you can find places that make black and white copies for 1 cent. We had been looking all over town for some spanish workbooks/texts to practice with but couldn’t find any. So we downloaded a couple of spanish books, printed them out and asked for them to be spiral-bound. The books ended up costing much less than buying them would have. Some of these places have large scanners too so you can make big prints too.
Feel free to share your printers or cabinas of choice.
