The flat is nicely renovated & decorated. The high ceilings give the flat a nice airy feeling with plenty of natural light, and blackout curtains if you need to block the sun.
Everything is modern and clean, there is a coffee maker with reusable filter, nespresso machine, toaster, electric kettle, and the basic dishes, pots/pans, etc. You will need to buy your own spices, oils.
WiFi is good and reliable. AC worked well. Power went out 2x in the month I stayed there, but restored fairly quickly (15-30mins). Washing machine is great, I hung everything up inside as it is very dusty outside (I recommend leaving the washer door open to dry before closing it to avoid mold growth inside) There's hangers in the closet and lots of drying hooks/racks in the bathroom.
Be warned, the main entryway door is very slim & heavy, the stairs wind up to the 3rd floor, and are steep & narrow. Be sure to use the light switch to turn on the timed light for the hall stairs, and mind your head as the ceilings are low (I bumped mine many times).
This is the perfect place for people who want to be in the heart of the action. It is very close to the beach, bars, restaurants & nightclubs. Since the beach area is a party zone, be prepared to hear a lot of noise until late night. You will likely hear the neighbors coming & going in the hall, and also if guests upstairs are heavy-footed. This is less a place to work remote if you need quiet, but it won't matter if you are on holiday and out to see the sights.
