Have you looked at the Hotel Belair? In my opinion, it is a better option than any of the hotels you have listed.
Art Hotel has doubled their rates since opening. Friendly people, but the rooms are small and the bathrooms smaller still. Long on charm, short on creature comforts.
LoiSuites. Great location. Rooms are adequate and the hotel is new. Nothing special
Etoile. A bid ragged around the edges. In dire need of a makeover...beds sag, the wall paper and carpet are dated, etc.
I stayed at LoiSuites over Christmas....I agree the location was excellent (even on a quiet side street, or maybe because I was on the Cemetery side)...I found the rooms to be adequate (carpets could use a little more cleaning) and the bathrooms more than modern and adequate...good buffet and the staff was very helpful. Would stay there again.
Another interesting option, especially for you that are coming in a group, is to go to the Art Suites; which is very close to the Art Hotel. They have excellent apartments, and their rates are very nice, the premium apartment that has room for four persons is around U$164 with breakfast and VAT tax included (In Argentina this tax is 21%), that is about U$40 per person. Because this hotel is in Recoleta, you are relatively close to all of the hot spots of this amazing city.
Check out the NH Jousten. You'll get more for your money there. The breakfast is phenomenol. The rooms at Artsuites are huge, but I find the ones at the Jousten to be more stylish. And while Recoleta is nice, there are few advantages to staying there. How many times are you going to want to visit Evita's tomb???
Palermo Viejo is where you'll really want to spend time, so it may be best to look there, either at the Malabia House or the Bo Bo.
I like the NH Jousten as well. Not all rooms are equal though, so ask to be changed if you don't like your room assignment.
I disagree somewhat about Recoleta. I like parts of Recoleta very much. Palermo Viejo appeals more to a younger crowd, so now that you are 30 you may find other areas more to your liking (smile...hey, it's intended as good natured ribbing so don't get too upset).....
I stayed at the Kempinki's Park Chateau. We booked through Expedia and got a rate of just over $40 CND per person. The hotel was nice and the area was nice, but our room was small and very dark. The hotel staff spoke excellent English, but I was disappointed to learn that when they booked us taxis, they ended up costing us twice or three times what the meter should have been! For instance, we were charged more to go a few blocks to the Colon Theatre than to travel right across town! For that reason, and that alone, I would hesitate to recommend this hotel.
First of all you were paying about 30 Us $ for a hotel in a nice area of town where they spoke excellent english and you are complaining the room was small. My god. In Toronto that couldn't rent you a closet in a bad part of town.
I recently returned from BA a couple months ago. I'm 31 and think BA would be a great place to celebrate the 3 oh. I stayed in Palermo at a nice place, Alpino Hotel. I went with my friend and we kind of stumbled upon it walking around Palermo. It's within 5 blocks of probably 10 different great resturants (and 2 blocks from the best dulce de leche @ persicco). I think the room was only like 45 bucks/night. Before traveling to BA I was excited about visiting Recoletta. The cemetary is worth every moment, but the neighborhood was the complete opposite. Very touristy and interestingly populated by strip clubs. I would not recommend staying there. Enjoy
What were the rooms like at the Alpino? The Bathroom, firm bed, size, English speaking staff, etc? I have walked by this hotel several times and wondered what type of place it was because the location is so good, in a nice part of Palermo.....
