Not bad overall, but some of the procedures were a bit archaic - like having to have the bellman accompany you to your room upon check-in whether you want it or not. Also, they want fifteen minutes notice upon check-out so that they can check your mini bar. Like many hotels, they ask for a credit card scan and authorization for any incidental charges over and above the Expedia pre-payment of room and tax. This is expected. What was unexpected and a bit disconcerting was to have the desk clerk manually write down my full credit card number, expiry date, and three-digit security code on the authorization print-out. In any case, and in fairness to them, no charges have appeared on my account - it was just something I've never seen done before.
The room was clean and relatively comfortable. However, there was a window with clear glass at the back of the tub in our room. (I expect this is not the case in all rooms.) You just needed to stay near the front of the tub while taking a shower unless you wanted to be seen.
Good location near the Retiro district. Breakfast was quite good.
If I had to stay there again, I could live with it, but I'd probably choose somewhere different given the choice.
