The best thing about this place was the location. You're walking distance to a lot of great tourist attractions and bars/restaurants. The building is also pretty charming, complete with one of those old wooden elevators with the manual glass window doors you close shut manually.
The biggest downside was the noise. Because you're in the middle of the city and it's an old building, you really can hear all the street noise quite loud inside the apartment. Also, you hear very clearly everything in the common area hallway/staircase, including the elevator which is noisy. None of us got a good night's sleep the entire visit. The description boasts a "noiseless street," but be aware this is definitely not the case. If you're a light sleeper, best to look somewhere else.
Check-in was also a bit odd and involved waiting outside for a quite a while with our bags, despite having advised her ahead of our arrival time, calling her when we were on our way (as requested), texting when we arrived, etc. Mar manages several Airbnbs in this same building and has to juggle getting them all checked in, so I'm imagining this is not an uncommon occurrence.
Photos are also a little misleading. Small touches like the plants and furniture are missing or different than in the photos. Feels more bare bones than it looks. Not a huge deal, but worth mentioning.
Overall, the great location wasn't worth it for us, mainly because of the noise.
