The mattress is too soft without much support and overall the cleaning lady didn't do a good job as many kitchen ware and cups/glasses remain greasy when we check in.
Sofa has unknown stains and floor is also dusty. We were also missing toilet papers on first day of check-in and Tanya/Alex crew even asks us to pick it up ourselves at their office and did not supply until we verbally complain on the second day.
Overall I am disappointed with the experience as Tanya/Alex is reputable given they managed large number of rental apartments in Prague. With US$120 per night of stay I would rather choose a hotel next time in Prague.
