I had the pleasure of staying 1.5 months in this apartment. It is well located and gives you quick access to the city. WIFI is very fast, and there is AirConditioning. The hosts are very responsive, an issue was quickly resolved the very same day. The apartment is not very well protected against noise, but contrary to other guests I found the location to be very quiet. I enjoyed my stay here!
Know before you stay here: The apartment is very dark; this also means it does not get very hot in summer. It also felt quite humid; there were some traces of mold stains in the bathroom under the silicon sealate, and the wooden floor gets sticky quickly. Unfortunately there was no vacuum cleaner or similar in the apartment when I was there; but I am sure that contacting the host would have resolved that issue quickly. There is also little storage opportunity, you might have to live out of your suitcase while you are here. This fits very well with my style of travelling, so it was not a problem...
I would stay at this place again with no hesitation.
