When we arrived, the receptionist did not speak any English (and we don't speak Spanish), so communication was difficult.
It is impossible to park in front of the hotel / appartment complex, and hence, check in was very difficult. The receptionist then charged us for the full stay although we had already paid at Hotels.com, and we thought we'd only pay for the garage fee and for the local tax. It's only that I noticed later, and then complained with the receptionist who then cancelled the payment. But what if I had not noticed?
The garage is super tight to get in, so it's definitely only possible with a small car.
The most dangerous thing happened at broad daylight, at 5 pm on our second day. You get a keypad code which is...insecure because basically, everyone who ever went there will know the keypad code for every appartment!
And on 5 pm, someone else entered our appartment, without any reason, a man ca. 35y old, without any excuse or any affiliation with the apartment complex. Sure he wanted to rob us, but as we were (luckily) both at home, we just yelled at the guy and he left. Definitely a bad habit by the complex!
