Ricks place is a great flat just one major block away form quaint Condesa/Roma and easy walking distance to museums and the METRO (which we did not use but saw it as we walked by).
The room was clean and well accessorized - and as others have mentioned in the early morning there was a ton of traffic down the street with cars honking constantly - not anything that can be done about that just an FYI.
During our stay there was a very loud gathering in the building on a couple nights. Again nothing that our host could do about that - I wonder if it was perhaps another AIRBNB in the building - not sure.
Rick was very quick to answer our texts which was appreciated. Easy to get around the city by using UBER.
I would recommend this flat for its convenience and closeness to a peaceful place in Mexico City.
