Do anyone here have ever been to the HERA Guest House, a student dormitory of the University of Warsaw ?
I know it a little, since I lived very near for several years.
As far as I remember it's for post-graduates. The building isn't very new (it's a 1950s hotel) and you shouldn't expect the rooms to be shiny and new. I would think it is very well heated in winter (this is normal in Poland). The big plus about it is that it's in the best possible location in Warsaw - in a good area, close to Lazienki Park and the Prime Minister's residence, as well as being a few minutes on the bus from the centre of the city
There's a hairdresser and a (quiet) bar on the ground floor, and a few cheapish restaurants nearby.
Usually, the lady at the door thing is for undergraduate dorms, more than this kind of place where you will find doctoral candidates etc who they tend to trust more. This does however have a hotel-style reception.
Hotel Hera is a place that most students would be very pleased to get a place in.
To add - I remember some building work going on there one summer and think that some of the rooms are renovated (as in the picture) but suspect not all. the bathrooms should be OK.
