I stayed with 5 friends for the World Cup so I'm sure my experience was different than almost everyone else's who stayed at this apartment. I found Valeria to be very communicative and pleasant, but I would say our stay was overall pretty miserable. For starters, we were paying $600 USD a night for the World Cup so it was a bit surprising to see that the apartment she advertises as comfortable for up to 6 guests was so small. There is a double bed, 2 single beds and 2 pull out style mattresses (if you want to call them that)--the problem is there is literally no floor space to put the pull out mattresses. On top of our surprise at the extremely depressing conditions at the apartment, Valerie sent me a message within 2 minutes of dropping our bags that we owed another $200 USD because we had an extra guest that we didn't mention in the booking (though she only has a $7 per guest per night fee listed on Airbnb). Seemed very strange to try to extract $200 more dollars on top of our $3000 USD booking. She said it was the standard fee for cleaning the sheets/towels (???)

Here's a quick rundown of the pros and cons of this apartment for future guests:

Pros:
-Great view - its plastered all over all the photos on this listing so you cant miss it
- Safe building with pleasant doormen
- Nice tv, if you care about something like that

Cons:
- Location is not very convenient at all - its off a main highway that is impossible to cross or get cabs from and there is no decent food that we could find within reasonable walking distance
- Incredibly small as I mentioned -- it might be a reasonable size for 4 people if 2 of the people don't mind sharing a small bed
- All of the apartments in the building are very close together - we heard some pretty unbearable drilling into the wall on our first night
- Wifi went down often. This was pretty unfortunate as it was our only means of communication with only phones from the US

I might recommend staying here at the normal prices with a group <5, but this was definitely the least comfortable apartment on our 3 week trip.
