Location is great, especially if you're into the night life scene. Lots of good restaurants, bars, hookah lounges, and crazy amount of gentleman's clubs just down the street. But it is surprisingly quiet in the apartment despite this, so don't let this deter you even if you have kids. We had 4 adults and 5 kids with us and never felt concerned or like it was a bad choice for the children.
The apartment itself is very large and nice, lots of bed space. No complaints there.
The hot tub takes a very long time and A LOT (if not all) of your allotted energy allowance to warm up. It was on for 24 hours before we could get in and it drained through our allowance. It also does not get very hot... Not jacuzzi or hot tub standard, more like a heated pool. We booked this place partially because of the hot tub, so this was a bit disappointing and we only ended up using it once.
There are a few hidden costs. There is no dish soap, hand soap or extra trash bags provided, so we had to purchase these (just to leave the soaps behind basically completely full when we checked out). We also had to buy toilet paper at the end because we ran out. You have a limited energy allowance which you have to pay him the difference for in cash, on top off the taxes and another fee you must pay in cash upon check-in (€31 for 4 adults).
Paul was extremely responsive to all of my emails and helpful with everything. Overall, a lovely stay.
