I stayed here for a month and really enjoyed it. Really good location, close to the metro and within walking distance from all of the main nightlife areas too. The balcony is the whole length of the apartment, and bigger than it looks in the pictures. Great view as well.
Some old reviews mentioned that it was a bit cold, I didnt find that but there are new air conditioning systems in both rooms (you can control from your phone) which works really well to heat the apartment.
Only issues that I had were the oven/grill didnt work while I was there. The rest of the kitchen utilities like the hobs, washing machine etc worked perfectly fine though.
I didnt find the street noise too bad, however the apartment next door is another (much larger) airbnb, and there were sometimes loud parties while I was staying there. They usually dont stay in the apartment too late though so its not too bad as long as you dont have an early flight!
Overall though this was a great apartment, and well worth the price!
