The building is really beautiful and the private suite we booked is really lovely and ginormous! The bathroom and Jacuzzi is really awesome. Our hosts are attentive and willing to help always! Kitchen is a shared space and quite tiny for the size of the building but its kept clean which is important.
The only thing we would say is that we thought we could survive the summer heat without air-conditioning but we found that in the afternoon, the room is really hot even with the fan. The evenings generally brings a nice cool wind and we had no issues with the heat at night.
Location wise, it is around 15-20mins walk to San Telmo market (good food, atmosphere and one of the best coffee we had in South America). Laundromat right opposite and public transport is close by too
