I would like to re-emphasise what the posters above me have noted - for me personally, of all ICs I have stayed in, this one has offered the best experience (and I am a simple Platinum Ambassador). Unless I am miscounting, I have 4 stays in the last two years (unfortunately lounge closed at all occasions), always booked the lowest category king room and upgraded to high floor with view of the Parliament / the Cathedral. Extremely good prices for IC (consistently sub-100€), easily reachable from the Airport (2 minutes walk from the nearest metro station or 6€ taxi ride), perfectly located, etc. I can only recommend it - and Sofia is worth a (long) weekend trip.
