The location of the space is phenomenal! A stone throw away from the U3 and right in the main shopping drag, if that is your thing.
The apartment is spacious with super tall ceilings which gives it a great feel. The washer/dryer was a great plus as this stay was in the middle of our 3 week stay in Europe and we packed light.
Thomas was really friendly and responsive when it counts, although there were a few times where a response took a few days. These were not time sensitive matters, just figuring out the logistics before the stay, so it was not an issue.
One thing that was a bit unfortunate was that there was a bit of unexpected noise from several sources. There's an Irish pub right underneath the apartment and on Saturday night this was a bit noisy. It didn't go past midnight, and the other nights were completely quiet (our stay was Sat-Tue). There was construction in the courtyard that started at 7AM, but that really can happen anywhere you stay. Other than that, it was remarkably quiet, even with the windows open, for being so close to all the action.
I would recommend this place, and it was definitely a good value.
