Hello, we are a couple traveling to BA and Mendoza in early April. Looking for decent hotels $100 US/night (or less). We are open as to where to stay, although in BA had thought Palermo, Retiro, Microcenter. Any recommendations greatly appreciated. Thank you so much.

In Buenos Aires, try Bellesuites, I love them, they are very nice studios fully appointed with maid service 7/7. Look at bellesuites.com.ar, they charge $95 all included for two persons.
Actually they are like any hotel , 24 hs front desk, etc

Question: How long are you going to stay? If you stay 7 nights as an example, you might want to look at apartments.
Roomier, and breakfast just around the corner, or make your own.

How long in BA, how long in Mendoza? There are some great places, but you have to be more specifice on dates and $$$$$.

Remember, most places you stay at will offer 10% off for U.S. cash.

Hello, sorry for not enough details. We are in Mendoza for 4 nights April 5-9. BA we hop around a bit, 2 nights at the start of our trip April 3 and 4 and then 3 at the end April 16-19. (A week in peru in the middle of that)

Hoping to keep the hotels to around a $100/night.

Thanks again for any help. I was in Argentina in 2003 and found this forum invaluable.

If you are looking for bellesuites, after all, I noticed that if you clic on the address it does not work because the ar at the end is left out. I guess you have to type the whole thing.

Thanks, I've emailed Bellesuites and waiting to hear back. Any thoughts on Mendoza?
