Pros: The location is absolutely unbeatable. You are in the center of everything, including Sol station, which is 3 min away, and can get you to the airport with just one transfer. You can go in any direction to find good restaurants. It is also near great shopping areas, and has 2 really good bakeries near by.
Con: The flat is facing the streets so it can get loud at night, from people partying to the garbage truck early in the morning (which sounds like a building falling down, it's that loud). The whole tiny building is other airbnb rooms, so you will hear people coming in and out, especially your neighbor. The room is like a studio with a spacy bookcase that seperates the bed and the sofa bed, so it is better for a family than 4 grown adults.
