Dirty! There was a lot of hair on the wall in the shower cubicle. The cups and plates on the kitchen had food on them and were sticky. I got bitten all over my body by bed bugs, causing an allergic reaction.
The host admitted that their maid had not cleaned the place properly prior to our arrival. I got a refund from Airbnb because this was unacceptable (the host did refund the cleaning fee but refused a full refund, however Airbnb gave that to me in the end).
Also, they need to make it more clear in the description that you need to climb a huge number of steep stairs to get to the apartment on the fourth floor, which is particularly exhausting with luggage.
On top of this, they accidentally gave me the keys to two other apartments which caused stress when I could not unlock the front door due to the mix-up.
The apartment itself is attractive, but extremely noisy at night due to the location (and that is not the host's fault).
If this place had been cleaned properly and had no bed bugs, I'd give it 4 stars. It would lose one star due to the huge number of steps and the noise at night.
