Hi Fanjet,
You are right about being way out of town; it will suit people who want everything on hand with no external noise etc.
My perspective on public transport from Modin Airport to hotel fairly easy you can purchase a combined bus/rail/bus ticket for 17 zlotys, but I had only a small carry on bag.
The next day it takes about 5 min walk to a bus stop, where you can catch a bus back towards the city but you have to change onto trams for about 4.20 Zloty.
Would not say it was too hard it took about 40 mins from bus/tram to city i.e. Central Station, but I probably would not fancy going back after spending a day sightseeing around Warsaw.

Hi Skimanant,
Diamond level through leisure stays been that level for last 4 years, booked a guest room in the sale for about 195 Zloty. Think that what I received although it did have dressing gown and slippers on the bed, 2 bottles of water and some chocolates on a dish. According to the elevators the Hhonors floor was on the 4th I was on the 2nd not far from lounge.
Hope this helps
Basset
