I'm happy with Aster City. My only real problem was a faulty TV receiver, given that my Polish was too rudimentary to risk a phone call I went to see them on Jana Pawla. Engineer swapped out the unit the next day at a time of my convenience. All good so far. Net side exellent, good fast reliable connection.
not sure what u mean Aster "City" but i'll tell ya i had Aster's triple-play(well.. double i guess cuz there was already a phone line).. 10mbps and about 30-50Basic channels(can't remember exactly) last year for two months and their Service was amazing!! i was always downloading at 1.2MB/S.... never any downtime(well... only once.. the speed slowed down for about an hour but was back then with no-further problems).. so basically.. Yes i'd advise you to go with their services....
as for me.. this Summer i'm trying to see if i can get UPC's 30mbps service in Krakow.. only got 9 days left till i travel :P
just noticed on ASTER's website.. they highered the mininum download speed from 512kbps to 1Mbps, and from 6mbps to 8mbps :)
