Cotroceni is a district just west of Bucharest's city centre which is best known for its green spaces and student population. Lot of and quirky bars and students.
You can move either in:
-Subway: The quality depends on the line that you are riding; some has old vagons, while other has really good and shiny new everything, in the new trains they are usually two security guards. The price is: 4.5 lei for two rides, but if you are going to stick around, I would recommend getting a 62 rides monthly ticket (it's 50 lei). Blackriding is easy to jump inside, but difficult for not getting catch (every station has two/three security guys and one/two administrative staff, I never tried, but people told me that if the staff sees you going in without ticket (jumping, going behind someone, etc...) an alarm goes off).
I've experienced in June 2015, that securities call after you, if they see you jumping over the gates, but they never run after you. Anyway, still try to wait until the subway is just arriving, to avoid any problems.
-Tram/buses: Fast but not nice and clean. Easy to blackride, lots of people do it. I recommend to buy a ticket from the little houses outside the stations and just hang around the validating machine if you see someone asking for tickets. In case of get caught, talk english/native language, and they will let you go (most of the times).
-Taxi: Is the most challenguing method for a foreign visitor. The usual price of the ride is 1,40 ron/km. If you are lucky, you get that much. But, an alarming number of visitors found themselves in situations that the taxi driver wanted to scam them; the methods can vary, either they turn off the counter (saying that it doesn't work, for example), add up some fees ( night fees, tourist route, etc...) or just want you to pay more than the price written in the side of the taxi.
You can find really nice hostels/hotels cheaply. From top of my head:
-Funky chicken hostel near Gara de Nord is 6 euros per night.
Please edit this page and add information about food.
In most of cafes or bars you can find free wifi. Springtime, Starbucks and Mcdonals are the classic ones.
Also, the metro has a wifi network free if you have contracted a determined provider.
If you need to use internet, in the Cervantes Institue, in the library (first floor) there's always an open pc, just don't look too shaggy and respect everyone.
Bucharest is a young and growing city and is becoming a popular destination. It is a great city for buskers, as they are well received, especially in the central older district of Lipscani. There is sometimes competition for space on the pedestrian streets nearby.
