My husband and I had some trouble figuring out how to get in. Here's what we found: When you arrive at the apartment complex, go through the outside gate. You'll see the pool to your right. Find their apartment building within the complex (Sonsoles will send directions the day of) and then ring the buzzer for their apartment.
Other than that, the room was very clean and we had our own bathroom. While Sonsoles has air conditioning, it can sometimes get hot in the room.
