It is a good location, near to buses/metro and walking distance of the city centre .
But there are big negatives. The apartment is located above a restaurant. Their extractor fan is noisy with equipment located right above one of the bedrooms. It turns on at 9:30am and stays on until about 9pm at night. Every night. It is loud. It is not possible to sleep with the noise or to stay in the third bedroom once it starts.
The toilet cistern has a constant trickle of water, located in a tiny room, unable to comfortably sit on the toilet and close the door.
We notified Sam who expressed surprise and said he'd fix them. Nothing was fixed, constantly fobbed off. Older reviews (which we'd missed) show these issues were months old.
Other issues: Sofa bed was grubby and stained. Toilet door handle was broken. Shower was a hose from taps in the bath to chest height. No lift and narrow stairs from street to 3rd floor apartment.
I cannot recommend this apartment or any dealings with Sam.
