This was a pretty good place! As others have noted, the sellotape on the cupboards seems unnecessary and weird. If it’s a priority not to have others go through your things, they could certainly be placed in a box in storage? I have also stayed in Airbnbs in which people lived normally and they simply didn’t bother with such ‘measures’.
The place is really central which is good for location but does mean you get a lot of noise at night. I didn’t sleep super well but was glad to be in the middle of all the action too (I had a conference a 5 min walk away).
So overall the flat isn’t super comfy, but functional. The steps aren’t as bad as others have made them out to be - it’s just a normal and even quite short staircase. The lady who welcomed me was friendly and addressed some of the issues mentioned in previous reviews (e.g. the dust that comes in if you leave windows open). It was fine!
