A wonderful and small hotel, only 12 floors with a couple of units per floor. Located in a centric area to the city and easy to walk to most of tourists attractions.
Breakfast was very nice, fresh and replenished all the time, we didn’t need lunch after it, maybe a banana or something small to tie us over till dinner.
Staff was very professional and willing to assist you at any time you pleased.
The only thing I would say, is that they may need to update the air conditioning units as 1st. room we had wasn't working but they changed us immediately; another suggestion will be for them to replace towel hangers in the bathrooms...a little upkeep will resolve this.
Overall, our stay was wonderful and staff always friendly and pleasant. We recommend to stay there, as we probably come back to Pleno Madero hotel next time we visit Buenos Aires.
