I have stayed twice already in this apart hotel. The location is great, very near Santa Fe y Callao ( prominent cross road in BA) and walking distance from Recoleta , Plaza Francia, the Recoleta Cultural Center, Museo de Bellas Artes, etc.
This is a condominium where a company is renting and managing some of the units, which may be a bit odd. Nevertheless, they hace a front desk open at business hours (Sunday is closed).
I had a couple of things that were out of order in the suite and ask them to get them repaired and they did pretty fast.
Wi-Fi is mediocre, but this is a problem in the whole city: some times you have good signal and some time it disappears.
Downstairs there is an excellent coffee and cake shop called Nucha, where you can enjoy the delicious local pastry, and at the corner Volta, which is a famous Italian gelato chain. Do not leave without tasting it!
You have on the same street a restaurant called Melo which has amazing food too.
The unit is well equipped and if you need something they can find it for you.
The only really bad amenity is the gym: it has a couple of old bikes and treadmills that barely work.
They called a car to drop me off at the airport which was much better than a taxi at the same price. (Try not to get taxis on the street, always get them by phone, because they may scam you, specially if you do not speak Spanish)
