Everything was excellent, these are the small remarks I did have though: only the floors under the beds were a bit dusty, and the toilet brushes sometimes fell apart. Also the bed/couch combi was broken so it could not have fit two people, no problem for us, as we did not need the extra space, but the fact that WE found out once there, instead of being informed by them, could have been a problem for a larger group. Lastly, you only get one set of keys, and you cannot open the main downstairs door without a key, so if you go as a larger group and you know you at times split up, one or more people staying behind without a key cannot actually get OUT of the building on their own, nor back in (duh). They do tell you this once you get there, and you can plan/work around it, but keep it in mind.
Overall though, we loved it, we used the kitchen for a great homecooked meal (though the biggest induction plate does not work, which should probably be fixed), everything needed for a good breakfast was present too, and having multiple working AC's was fantastic. The person who let us in was also helpful, talkative, but also concise and knew when we had heard enough, before answering some of our questions about the city.
The location is also fantastic, you are near the main bus/metro line from and to the airport, and in the city centre, near some great places for food or to start a stroll through town. The main bridge and the district with the port breweries are also around the corner on foot, it's genuinely fantastic.
