We had a lovely experience. The place was very nice and comfortable. The entrance was secure. The apartment was quite a ways from the end of the subway and we had to figure out the bus schedule at the last minute. After a full day of traveling, it was more stressful than it needed to be because of her lack of communication.
After our arrival and settling in, she was more responsive and checked in on us often.
We had a great place to stay. The only thing I could recommend would be for Sandra to be more quick to respond and to give more information in advance about traveling and check in/check out.
I admit these things may be common knowledge that I was unaware of, however I did feel more nervous and stressed out than I feel I should have.
