Buenos Aires Accommodations: Intro
Accommodations in the capital range from 7-buck-a-bed youth hostels to palatial luxury hotels, where a night's sleep can set you back the better part of a thousand dollars. Midrange hotels (in the US$50-100 range) can be a particularly good value, and frequently offer more intimacy and character than their more expensive (US$100-200) brethren. Travelers looking to save should have no trouble finding budget rooms for well under US$50.
A two-tiered price system has sprung up since the financial crisis, so expect to pay more than locals do for a room. Feel free to negotiate, though, if the place seems empty and especially if you're paying up front in pesos for a longer stay.
Be aware of the standard 21% tax on accommodationskn known as IVA, or impuesto de valor agregado. It's often left out of the advertised rates.
The hotel star rating system isn't consistent enough to take seriously, except perhaps in the case of 5-star hotels.
Booking in advance can certainly score you a deal on hotels in the expensive and luxury categories; in cheaper places you'll likely get a better rate just walking in and bargaining, rather than locking yourself in early at their "rack" rate.
