Stayed there during Christmas period 2021. Really loved staying at SACO Holborn - great location, near Bloomsbury Centre and a walk distance from Russel Square/Holborn stations. The staff were nice (except the cleaning ladies) and welcoming and made my stay easier. The furniture is nice and modern. I would recommend reviewing the cleaning policy: I stayed 10 days in one flat and even after requesting, the cleaning lady only stopped by when we were moving out to another flat. Also, there was a lot of dust in the flat, the toillets were dirty (with someone’s remainings) and we found the fridge with food stains
I had to complain but even so, the new flat was also dirty (under the sofa was disgusting).
It’s a bit pricy for all this trouble, but has a great location.
Would recommend for someone that would spend more time out than in.
