This was my first time using AirBnb and it was a very good experience.
Hanna was very responsive to questions prior to my trip. I was getting in to Munich prior to her getting off work but Hanna was able to get me checked in with the help of one of her daughters.
Accommodations: Very clean. The bed was very comfortable. Loved the view off the attached balcony in to her yard. Also was thankful for her having bottles of juice and water in refrigerator located on the balcony (for low cost) after long flights.
Bathroom was VERY spacious. Lots of water pressure.
One thing to note. There is a spiral staircase you need to walk up/down to the room. I didn't have a problem with it, but some may find it difficult to get heavy suitcases up to the room.
Location: Easily accessible by U-Bahn. Approximately 3 minute walk to her house. Took approximately 16-18 minutes to get to Marianplatz. The neighborhood was very quiet both at day and night. Felt very safe walking through it.
Overall, I would recommend the room if you have plans to visit Munich.
