Super recommended! Concha is really helpful, we let her know that wifi worked great in the living room but it was weak in the main room and next day she bought an amplifier, the situation was 100% resolved :) Also worth mentioning that the location is great, just 1 block from Parque Retiro! The apartment is very well decorated.
I don't give a 5 stars rating just for one reason, the power/energy capacity is limited so the electrical breaker trips VERY easily. This was annoying because they placed a big heavy mirror right where the breaker is so to reset it we needed to remove the mirror and then place it back again...and this happened at least 4 times during our stay.
