We were five (2 couples and mother/mother-in-law) and Romana's place suited us fine!
The location couldn't be beaten - we even had a view of the church in the Old Town Square!
It's 2 stories, and my wife and I had the loft bedroom - no probs. Nice to be able to open the windows and have the view.
The additional bathroom was such a help.
Everything you could want - good wifi, fridge, cooking/cutlery/crockery, towels and linen.
The building was old - but Prague is an old city. Romana's place was very clean and comfortable and we were very happy here.
