We had a great time at Thomas' in Mexico City. The apartment is very well located in Roma/Condesa - it's really near lots of nice restaurants, a supermarket and a short taxi ride to Centro Historica.
The apartment had everything we needed for a three night stay and is very comfortable, it even has its own courtyard space.
Thomas was very helpful - he got up at 4.30am to welcome us from our flight and let us check in very early. He gave some very useful recommendations and was there when we needed him, but let us be.
I would definitely recommend this accommodation to a couple looking for a relaxing place (sometimes with live opera music in the background) in a very busy city.
