The aim of this post is to talk about important information about Buenos Aires, for example if it is safe, how does tip work, electricity, wifi, amongst other topics.
In other posts we talk about the weather in Buenos Aires, how to get around and how to get from the airport to the city.
Between Argentina and Uruguay, where two rivers join, Uruguay and Paraná, the delta of Río de la Plata is formed. Considered the widest river of the world with 219km, Río de la Plata divides both countries. On the map Río de la Plata looks like a wide mouth that opens to the sea, and on its coasts you will find Buenos Aires, Colonia and Montevideo.
In Buenos Aires you will find two different airports. One for the international flights, Ezeiza Ministro Pistarini; and the other one for domestic and regional flights, Jorge Newbery Aeroparque (Brasil, Uruguay, Chile and Argentina). This last airport is located in the city, but Ezeiza is located 30km from BA and its accessibility is a bit more complex. This is why we are going to review a few options you can take to arrive to the city.
The very first thing you need to do is get a SUBE card. What is it? Well, this plastic thing. 
You will need this magnetic card to pay for all public transport in BA. Without it you will not be able to pay, so getting this card is vital if you want to take a bus or the metro.
Buenos Aires is overwhelmingly big, so as you are planning your visit, you might feel a bit confused as regards where to stay. If you want to stay in safe and easy-to-get neighborhoods that are near the main attractions of the city, this post has been written for you.
Buenos Aires is the largest city in Argentina and is located on the banks of the Rio de la Plata, this creates an environment with high humidity that is suffered a lot in summer with high temperatures and in winter because of the cold weather.
We were used to pay tickets with coins because the ticket used to cost less than $1 (argentine peso), but nowadays coins are useless because of the devaluation, the government decided to install a new system to pay transportation in the city. This is when the SUBE card was invented, a card to pay buses, subways, trains and even highway tolls.
