Neat little hotel about two blocks from the Florida Pedestrian Street shopping area. We had a very small room that had everything we needed.
I understand the Ikea catalog comment made by another reviewer. Obviously a lot of care has gone into a design remodeling. Pictures on the internet are exactly what you get. A low slung bed, a single bed table, writing desk with TV were all attached to the walls, light wood floors and trim. Desk chair wasn't a chair, but a space saving stool. Single floor to ceiling window with electric operated blind. Equally tiny bath managed to have a toilet, a bidet, a tub and a small sink (about 20 inches wide by 12 inches front to back), and was definitely a single person space!
Internet was included with a free cable and converter plug. Breakfast buffet was adequate, but no great shakes. Front desk staff was outstanding, provided help with phones, phone calls, and air conditioning unit.
Better maintenance would have allowed me to give a better overall rating but we experienced two major flaws. (1) the A/C unit wasn't cooling the room. The hallway outside was cooler than our room. Front desk staff did do something to cool the room but the a/c unit dripped condensation water all night long. We actually had to put towels on the floor to clean up the area and deaden the drip noise. And the area was between the bedroom and the bath, so it was extremely bothersome. (2) the shower didn't work at all. The plunger on the divert spout moved, but did nothing to start the shower. I don't expect these problems to continue, we just had an unfortunate experience with our particular room. Given the price and the location, I would probably give this hotel another chance.

This hotel is a very good one. Pleasant staff, very good breakfast and brand new furniture.
Always clean and linens changed every day with care. Bathroom clean and with good conditions.
It´s very well located with easy access to calle florida and sightseeing bus. Remember, it´s location is in the center of the city, and as in any place in the world at night this place is strange.
If you want to stay close to bars and night parties, choose another place or walk with cab.
The internet work poorly in the rooms, so you have to go to the lobby for email reading. This is very bad after a full day, but if you´re on vacation, why care about?
Overall, a good place to stay in center of buenos aires.

Despite receiving a reasonable recommendation from a friend, we found ourselves disappointed staying at Vista Sol Buenos Aires Hotel Design. The hotel is well located in the Microcentro, the downtown BsAs, close to Calle Florida and Casa Rosada, in the same neighborhood as many other hotels.

The hotel was recently remodeled and the rooms offer decent features and was clean and modern. Still, customer service at the hotel lack on customer service training and did not offer consistent advices.

We asked for a possibility of a late check out (our flight would leave at 7pm). In the morning of, the front desk person (he was alone) said "it's possible, upon a US$25 fee up to 2pm". Excellent, we said. We will take it.

Later that day, one other member of the group (we were in two couples) went to double check and another front desk person said "it was not possible at all, who gave you this information?". We explained the situation and the answer was literally "he was NOT allowed to give this information, I'm the one who can tell you".

We tried nicely to negotiate and he was clearly trying to show "who was the boss", actually not being nice at all. We got very disappointed on our stay and with the lack of courtesy and somewhat politeness. We answered back to that, but in the end, just thanked them and decided to NEVER come back. Buenos Aires is totally worth the visit, but look for another hotel!

The hotel is ideally located in the core of Buenos Aires "small center". Rooms are large and full of light, their modern design include a lot of wood. Beds are XXL, so are the breakfasts buffet. A excellent choice for staying in BA.
