I've visited Buenos Aires about a half-dozen times, and had always wondered what this hotel would be like. Its location is wonderful -- in my favorite part of town, relatively safe late at night. I've stayed in other hotels, rented apartments and stayed with friends in this city -- on Vicente Lopez, even -- so I have something to compare my experience to.... The worst thing about this hotel was that the heating system in the room did not work. The manual control -- for which there were extensive instructions -- did not work, so I had to call the front desk to change the temp. I asked for 1 degree change in each case. But.. the room was either freezing or too hot after each time it was changed. I called at least three or four times, but after that, gave up. It was VERY UNCOMFORTABLE. (At first I thought I wasn't doing something right, but the clerk at the desk told me the only way to adjust the heat was if it were manipulated through a computer.)The next day, I remarked on the experience, but I paid the full rack price -- $147 for the room, but by the time the more than 20 percent tourist tax was added in (and a few local calls), the total bill was $180ish.
In Buenos Aires, it's possible to stay in a comfortable place for far less. Try the Wilton on Callao, for example, which is not in as good a location as Loi Suites but is about half the price, and fairly close to the heart of Recoleta.
I will say the Lois Suites Recoleta staff was very polite and the breakfast by the pool was very good. In my short stay (one night), I didn't have a chance to use the pool, but had I stayed through the weekend, I would have found that the pool was not going to be available to guests anyway (another ripoff, I think). Anyway, the pool is close to the dining area, so who wants to be watched by a bunch of diners when you're splashing around? The pool and the dining area are in what seem to be a sort of aviary... very attractive to look at, overall... The room itself was nice; there was maid-turn-down service in the evening, with a chocolate on the bed cover, and there was a well-stocked mini-bar. The guests, when I was there, seemed to be mostly Americans.
One other inconvenience: There's no ATM in the hotel, and you have to go across the street to Recoleta Village to use one. I think that particular ATM is in an incredibly exposed area, not the best place for tourists to be withdrawing money.
I would like to recommend this place as a good first stop for a new visitor to Buenos Aires, but I feel terribly ripped off after my own experience here.
