This was a modern hidden studio apartment upstairs of a mobile phone store accessed through an unassuming door in the corner. The original façade of the old building was untouched, but the insides were renovated.
Plus: location was as central as you can get (maybe a little "too central"?) Window facing the castle. Studio felt very modern and probably remodeled not very long ago.
Even though address was given in the email, some basic descriptions of the place in the email would've helped because Google maps sent me to the OTHER nearby (wrong) location when I just searched the name (there were multiple locations in the same areas). There were some homeless people loitering near the entrance and smelled of urine at the entrance.
Walking in the studio. almost every other step generated loud creaking noise. They did not reinforce the old floor before covering up with new flooring. Thankfully it was a mobile phone shop that wasn't opened in the evening. But because of that, it affected the stay experience.
Second complaint was the stairs. Not easy carrying my big luggage up since there were no lifts/elevators.
Maintenance was feeling a little off, one of my bedside lamps did not work.
Due to the apartment being a little warm, I had to open the window to get some fresh air (no air conditioning, but ok). However, being so central, and only on the 2nd floor, I can hear people talking loudly and traffic noises all the way until it died down in the later hours.
