We stayed for over a week in Claudio's apartment and enjoyed every minute of it. Check in was easy and the building and car park are very secure. The location is amazing: right in the heart of Condesa. Easy access to lots of restaurants and bars. The street is not busy with traffic, so it is quite peaceful.
The apartment is beautiful and finished to an excellent standard throughout. There is netflix with a big screen so it is great for a night in when the city life gets hectic. Bathrooms and kitchen are good specification and very clean.
The apartment had beautiful flowers on arrival and the friendly guard (Chapul) brought us some cakes one day from the local bakery. There are great guide books in spanish and english which we enjoyed.
I highly recommend Claudio's apartment. We had two couples there and it felt very comfortable.
