Arévalo / Ministro Carranza
There is a consultorio located on the corner of Arevalo and Arce (near Ministro Carranza subte linea D) , with a fantastic selection of chicas, including:
Rocyo

Lara

Angelina

Veronika
http://www.todomasajes.com.ar/bk/veronika/bk00.htm
At the very top of the list is Rocyo, who is a prize catch for this relatively quiet area (Belgrano / Caٌitas doesn't really have a great pick of the chicas). Angelina is mindblowingly good with the massages (and very good with the additionals as well). Lara (also known as Sophia) is the long-term resident here, and she is also excellent with the massage and additionals. If at all a weak link, Veronika is also very good, and she looks much better in person than those crappy photos on her page.
In all, two queens (Rocyo / Angelina) , two princesses (Lara / Veronika).
All of them offer very good quality massages, excellent shower facilities with towels that smell good and fresh.
Extras: CBJ (a little bit of almost OWO to start with before the shower cap goes on) , DATY if you're a giver, and a good 20-25 minute romp around. The back door is firmly closed. All girls offer only servicio convencional.
Prices: 150 for a 40 minute massage + 50 for just the CBJ + 70 for the complete package. Total of ARS270 for an hour (ish).
I can no longer be arsed to go out to Tribunales, where the pick of the masajistas who offer more are. Plus the quality of the massage is quite good here. And Rocyo and Angelina are as good if not better than many downtown when it comes to the garching.
Hope this is useful to you guys.
