I stayed at Gladys's for 2 weeks in Dec 2022 to work and study Spanish. The apartment was as described and had all of the basic amenities listed, but nothing fancy.
The location is great- in a very safe neighborhood, right next to the metro & in walking distance to tons of good restaurants and cafes in Condesa/Roma. The apartment does not have a washer, but there was a place just around the corner to get laundry done. The hosts were very friendly & responsive, and the internet was good.
A couple drawbacks were that it was very loud, both from the street noise at night as well as neighbors teaching Spanish classes during the day & partying at night. Also there is very little natural sunlight, making the unit extremely chilly (there is no heat). On top of that, the shower had only a minute or two of hot water when I arrived. After contacting the hosts, they did eventually send a plumber to fix it, but the water pressure remained so low it was hard to ever take a satisfying shower.
