The location was very good, close to the U-bahn station, many parks, and a full range of stores and supermarkets, all within a 5-10 min walk.
The apartment was perfectly clean and everything was in absolute order, but behind this was micro-management and miscellaneous rules (especially in the kitchen) that could be overwhelming for someone who prefers a more easy-going atmosphere. Barbara skimped on a lot of things that a traveler normally would've imagined included, or at least the host would be willing to share (e.g. salt). Quite confusing was that she sometimes was also generous that she shared her food with me and brought me a fan during the heatwave. But starting a conversation with Barbara was always easy and up-lifting (only in Portuguese or German though). I would still recommend a short stay.
P.s. for the previous guest from Denmark, Pil: I checked-in that very day at 13:00 and she was actually there. I noticed the luggages right away when I entered the house. She explained to me that those belonged to her friend (you) and she (you) would come later with her (your) own keys, so there was no need to open the door for anyone, even if the bell rings. I couldn't quite understand the logic behind this but I didn't give it a second thought since she started to show me around the house already. I am sorry for what happened to you.
