Great apartment, poor management.
The host changed us to apartment 5.2 instead of 2.1 in the same building, because he said 2.1 had a prolonged stay. (He also said that about a separate property we tried first. Coincidence?). He said 5.2 is exactly the same but it is not - it is darker with smaller windows and slightly smaller without the concave wall/sitting area. 5.2 is also under the roof so there are beams to duck around and it was very warm in early June.
Also, there was no WiFi code provided in instructions nor in the apartment. We asked the neighboring AirBnB apartment run by Chris and they also had no instructions in the apartment. His instructions said he would be available by phone from 8am to 6pm and yet he did not return our multiple messages until 3pm. This was a problem since we had business to take care of.
The apartment is clean and nice but it seems the host is more concerned about securing his next customer than taking care of the current guest.
If you actually get apartment 2.1 and the internet code, then it's a nice apartment with a great location. Do not accept apartment 5.2 at the same price because it is not the same.
Note also: this is an "active" neighborhood with the tram going by outside the windows and a late night restaurant making noise. The host says you can close the windows and use the air ventilation system but we found this insufficient in early June.
