I didn't meet Olga but her brother Alejandro was very helpful. The place is spotless! This is a flat with two rooms that are rented out, so you will be sharing a living room, kitchen and bathroom with the other guest. It's a pretty residential area, 8 minute walk from the closest metro station (Gran Plaza) which is 3 stops from the centre. Lots of shops down the road however. The only negative was that I found the mattress too hard but this may be personal preferance.
