I've stayed in many small AirBnB apartments in Prague over the past year. There are two general types: (1) owners who are really trying to build a brand, differentiate based on superior quality and service; and (2) owners who do the minimum, create nice pictures, but don't really provide anything special. Unfortunately, this apartment falls in the second category.
There were many small issues that you don't really notice until you stay at this apartment that, taken together, made the stay less than enjoyable. It wasn't necessarily the owner being inaccurate in his listing. Just the overall experience was not great.
First, let me say Artem was very friendly, responsive, and the check-in with him was very nice. He helped with luggage, etc. He seems like a nice guy, and I really wanted to like this apartment! But unfortunately, I didn't.
The building is not in great shape. There were two huge, overflowing trash cans at the entrance. The entrance hall reeked of trash. The elevator doesn't work, so you'll need to go up two flights of stairs. Not a massive issue, but with a small child and luggage, not so convenient.
The area around the building is very, very noisy at night. There is a youth hostel across the street, so lots of drunk college kids coming home at 2am or later. Even worse, two separate car alarms went off at night, waking my wife and me up. One at 2:30am, the other at 4am. Of course they didn't just go off once. They went off multiple times, usually with a 2-3 minute break. It was awful. The apartment is hot. So in summer, you'll need to keep the windows open. It makes the noise problem much worse. I was exhausted in the morning, having slept terribly.
The kitchen looks nice in the pics. The sink, however, is miniscule. You can't easily wash anything without getting water everywhere. It's not practical. The faucet on the bathroom sink was loose, giving a general poor quality vibe. The soap dispenser in the bathroom broke, the nozzle simply fell off (but we fixed it). There is no washing machine, although there is a nice space for one.
There are no lamps in the entire apartment. Only the main ceiling light. And that light was "soft". So forget about reading in bed. It's all or nothing when it comes to lighting in this apartment!
The curtains were thin and blocked almost no light. There were no proper blinds that could be closed. So you definitely don't have the feeling of privacy. And if you wake up with light as I do, you'll be waking up around 6am...
I can't really say Artem misrepresented his flat. But these little items, which you don't notice until you stay there, really add up. He needs to invest more in the place to make it enjoyable, not just provide the minimum. Regarding the noise, unfortunately I don't know what he can do, sadly. But I need my sleep, and I definitely did not get it at this apartment.
