The staff was very nice (and there were a surprising number of them). The courtyard is beautiful and the pool is so so. I liked the bed (firm) but the pillows were pretty bad like someone had cut up a foam mattress into pieces and stuffed them in a cotton sack.
We stayed for 4 nights, which is way too long in Asuncion...not much to do. However, the WiFi was really good and we were able to get some work done. Also, the breakfast is decent and you can get a buffet dinner in the hotel for very cheap.
The worst thing about the hotel is that there was some sort of party on our third night...maybe a bachelor or bachelorette party? Where were young women and men...but the party didn't start until about 3:30am, when they raucously and apologetically blasted music and drank in the common space (and RIGHT outside our room) until 9:00am. Obviously they woke us up and they refused to be quiet when asked. I said something to the desk clerk and he indicated that he had control over it...? I felt terrible for the cleaning staff because the entire place was trashed by the time we went to breakfast and they were cleaning it up (while the party was still going on BTW).
If you're concerned about safety at all, don't be. There is an armed guard outside.
