I stayed at Irina's for about a month - it was roomy with great location in terms of transit and laundry. The roof access and fire escape were great too! There were a few items not included I needed to purchase, such as dish soap, extra toilet paper, and garbage bags. As a host, Irina was responsive.
The bedroom was big and clean, and AC was great. Kitchen and bathroom could have used a deeper clean before arrival, and the bathtub had trouble draining quickly. (The taps are also reversed for hot and cold!)
The kitchen is large but doesn't have a lot of counter space, so not recommended for a lot of meal-prep. The stove was slow to boil water and the microwave was missing feet (so it was not level and the plate didn't spin) and the clock on it was broken. Oven worked fine and there were lots of plates and cups to use.
In the lobby and hallways, I saw three roaches (one dead), and two inside the apartment over the course of the month. There was spray available that deterred them for about a week when applied to the source.
Overall, for my needs as a temporary student not spending a lot of time in the apartment and the low price for an extended stay, it worked perfectly fine.
