The room I stayed in had a heater right next to it -- since the thermostat was set to a high number, the heat was on all night long and makes it rather uncomfortable. The heating system is not as efficient since it requires a lot of heat to make the rest of the house warm.
Otherwise, it would be somewhat less than clean if someone was a neat freak. It has an overall bare appearance and could use a little bit of color on the walls or at least some more light fixtures, as it was dark in the daytime inside. There is a lot of good potential if someone takes the time to upgrade it slightly -- it just seems like the place is really only a dorm or halfway house kind of place. If you keep your expectations low, you might be pleasantly surprised.
