I stumbled upon Tailor Made Hotel in Buenos Aires web page.
http://www.tailormadehotels.com/eng/Boutique, white, minimalist and looks like an excellent option located in the Palermo district of the city.
The boutique hotel only has 5 rooms but in the normal room rates the following is included:
Daily Breakfast
IP International Calls to 35 countries
Mac Mini on all rooms
Wifi through out the hotel
Laundry
Bike Lease
Snacks and Beverages
Wow! All that, I think is a great deal for the prices I'm about to mention.
The hotel has only 5 rooms all with queen beds. Rooms 1, 2 and 3 seem on the smaller side. Room 3 has alot more room that the previous and Room 5 is the largest with it's own outside terrace jacuzzi.
Rates vary per room but there is a special of pay 4 and stay 5 nights (20%) off.
Rooms range from $139/night to $219 for Room 5. If you do the 4 night package take 20% off the prices I just mentioned.
Have a look at the web page, it looks really nice and I hope to personally review this hotel and meet the staff on my next visit to Argentina (which is not in the plans yet!)
