Just wonderful! Luba is a fabulous host - full of local knowledge about Buenos Aires but also unintrusive and respectful of privacy. She is an immensely kind, tolerant and generous-hearted person - it felt like staying with a good friend in a genuine Argentine home. Luba is used to people who don't speak Spanish, so Brazilians, French, English-speakers and others would have no trouble staying there. Her spacious apartment is located on the edge of a trendy district of BA with lots of restaurants and cafes in walking distance. It's easy to eat out nearby even if you are a solo female traveller. The apartment has good wifi and transport links - about 5 blocks to the "metro" and plenty of bus stops that are even closer. BA is a noisy city so bring earplugs if you are a light sleeper - the traffic didn't bother me though and I slept well in my comfortable room which even had a TV. Great to wake up to her continental breakfast too!
