Mauricio was the perfect host and we stayed with him on two occasions. He went out of his way to greet us on check in and see us as we left. He gave us lots of good tips on where to visit, made us a lovely fruit and yoghurt breakfast every day and let us use all the communal rooms in his apartment, The location was very convenient for the main park and museums. It was situated in Condesa a fabulous area full of lovely cafes and little shops and very green and well cared for. We loved it and Mauricio was awesome, he could not have been more helpful and friendly. He even booked and paid for some bus trips for us as we were finding it difficult (we refunded him of course).
I would highly recommend this apartment as the best place to stay in México City.
