Although he wasn't there in person, Mathiaes was an excellent host and was very quick to respond to any queries we had during our stay, and made excellent recommendations. The apartment was clean, the bed was comfortable, and we were able to walk everywhere as it was so centrally located. The journey to and from the airport was made easy by by the metro being a 5minute walk away. The only drawback is that you can hear a lot of noise from outside and the other apartments in the same building (we weren't even there over a Fri/Sat evening), but earplugs were provided so it didn't bother us! I would highly recommend this apartment.
