I stayed 5 days at Andrea's place in August 2022 as part of my months long trip in Europe. Andrea's studio wasn't dirty in the sense that there were balls of dust or rubbish all over the floor. It was when we ran our fingers on the window sills and saw our fingertips blackened with a thick coat of dirt, looked closer and noticed a cigarette butt wedged inside one of the cracks, picked up the plates and utensils and felt the sticky slime on their surfaces, opened the microwave and saw the food stains splattered inside, opened the fridge and saw the film of grease on the shelves, bits and pieces fallen from a pot of dry flowers and just piled up on the desk, that's when we said to ourselves that this place hadn't been cleaned properly for a long time. We thought, fine, and just cleaned up the things that we needed to use and then proceeded to spend a few wonderful wonderful days in Prague.
However, two days after we checked out, I received a short and pointed message from Andrea asking me to explain why there was a strong cigarette smell and cigarette butts in the studio. That's when I gave her the above feedback. She said sorry and that she would speak to her cleaner to investigate. Apologies accepted. There were things that we couldn't clean for her, like the white stains on the sofa, or didn't know what to do with, like the dead plant in a bottle of very stale water sitting on the dresser.
The studio is centrally located but is indeed noisy with traffic starting early in the morning like others have commented, like 7 am. I was ok with that but people who are sensitive to noise should know this. The portable air-cooler is noisy but ineffective. We left the windows open and were glad it wasn't too hot in Prague during our stay. The door lock was indeed hard to turn like so many other people have commented. I work out and have strong hands. Yet sometimes I turned the key so hard that my fingers hurt and the lock still wouldn't turn. It took real patience and strength to turn it each time we returned to the flat.
Prior to our check-in Andrea messaged me saying that she's on holiday and asked me to go to a restaurant about 10 mins from the property to collect the key. That was fine by me.
