Stayed at this place for a few days around new year 2007. It's in a pretty cool location for Palermo and walking distance to the attractions in the area.

But I could only recommend this place as a back-up. For what you get the price is only so-so. I was traveling with a friend and we found that the room was pretty small. This my not be the case for a couple, but for two adult men the hotel was very small.

Also, while the Argentine staff was helpful, the owner was a bit annoying and gave me sort of a hardtime time regarding the price of the rooms the hotel had garunteed by email. When it came time to pay he told me what a great deal I had got and how prices had increased since then.

Overall, I didn't get a good feeling from the ownership. That said, the place is decent and is stylish and relaxing. It's not a terrible hotel, but I think they could work more on customer service from the managment.

In sum, I think there are better choices in the area.

I got into BA and to the hotel at 11pm on New Year's Eve. Next thing I know, I have a bottle of wine in my hand. What could possibly go wrong? Great staff, friendly guests, awesome area. Highly recommended.

During our trip to Argentina we came a couple of times back to Buenos Aires and we stayed in Costa Rica 3 times (6 nights in total). We stayed at several other hotels in BA as well, but the value for money ratio of Costa Rica can't be beaten! It's a nice and trendy place without becoming 'too cool'. Staff is very friendly and giving the place a nice personal touch. Emiel and Karin from Amsterdam

After reading the glowing reviews of Hotel Costa Rica, I expected something better. Our room (Junior, $70/day) contained a king-size bed, 3 nested end tables (no drawers or shelves), a suitcase stand, a wastebasket, and a small curtained alcove with a 3-foot clothespole. Period. There was a 2-foot clearance from bed to wall on the right, 3 feet at the bottom, and four feet on the left. What the room did NOT have were: TV, dresser, shelves (no place to unpack our suitcases onto), carpet (bare cement floors), mini-bar, telephone, hair dryer, Kleenex dispenser, shower curtain, bathmat, sill around shower (the water just flooded across the bathroom floor), facecloths, bathroom exhaust fan, drinking glasses, towel racks (two metal pegs were provided for our 4 towels). The bathroom door was of cloudy glass, and missed the bottom of the doorway by 3 inches and the top by a foot, so did little to keep light, sounds, odors, or stream from coming into the bedroom.
The staff were uniformly friendly and helpful. After 3 days we were able to transfer to a Superior room ($95) which was a good bit larger, had marble tile floors instead of cement, a chair, and a large armoire with 4 shelves and a large drawer. However no closet, so our hanging clothes had to be laid on shelves. And as with the first room, there were large unpainted areas on the wall, presumably resulting from plumbing changes
All in all, I wouldn't stay there again. We tried to locate another hotel in the under-$100 price range, but with high season coming on, that wasn't possible.
If anyone plans a stay there, I'd be happy to share info on local restaurants.
