I had a lovely time at the garden apartment at Casa Luna.  It was quiet and peaceful and I loved the beautiful garden views and visits from Mr Maximiliano.  The location is great with bus and subway connections close by, several milongas within walking distance, the self contained kitchen and bathroom were perfect and I felt safe and secure. It’s not in a real touristy location so prices are reasonable in the area for restaurants etc. 
Rob & Vicki freely offer their help and advice on everything anyone could possible need including changing money, taking me to the milongas, even inviting me into their home for private house parties and  dinners… and Vicki is an amazing chef (I’m still thinking about the roast chicken).   If you want somewhere to stay in BA where you can have privacy but not be totally alone then the Garden Apartment at Casa Luna is ideal! 
Thank you Vicki & Rob!!
Ciao & besos,
