We did not meet Carlos but met the other guys that worked in the reception and really appreciated their help and support during our stay! They only speak Spanish, btw. Carlos was really helpful prior to our arrival and during our stay for any random questions that we had. As for the space, we really enjoyed the simplicity and the natural light that comes in! It's located in Condesa and fairly centrally located to area stores and places to dine. I think we explored all the corners of Condesa =) Some things to note in the space ... I'd recommend traveling with your own bathing soap. Towels are provided. The bed and pillows in both rooms are very firm. If this is okay with you, you will be fine. The wifi was not always strong and reliable during our stay so plan accordingly. Do not hesitate to ask the reception for help ... broom, mop, iron is not provided in the space but you can request from reception. There isn't AC in the space, so we appreciated the windows. We really enjoyed our stay and appreciate the great location!
