Just a small note to anyone that is coming here, it is colder than you think! When I was packing before I left for Mexico I was like “Mexico, should be hot there right?”. Wrong! During a day in Distrito Federal (or Mexico City as we call it back home), you will normally experience 3 seasons. During the night and in the morning it is pretty cold, and then at noon it starts getting hot (20-25 degrees), then during aug-oct it has been raining a couple of hours every day. So if you think you’ll escape the rain from Gothenburg, that is not going to happen!
So remember warm and weatherproof clothes!
