Hi - I am looking for a serviced apartment in London for 2 months, around Marylebone or Holborn, or even Kensington South.
Can anyone recommend companies to use to book...i have read some stories about some not actually caring about the properties once they've been let. Citadines and Wilde have popped up for me which seem okay. Plum and LondonServicedApartments also come up in my searches but i'm not sure how these ones run.
Any recommendations for me? Even if its names to steer clear of.
Many thanks

You won't want a short stay property (i.e. like Citadines) because they charge higher rents for mainly short term leisure travelers. You'll need to look for long term agencies/properties with terms like "corporate rentals", "executive housing", etc.

Here is one such agency https://londonservicedapartments.co.uk

I’ve stayed in three of the Wilde hotels and I like them but the apartments are more like rooms with kitchenettes and I believe they only clean every four or five days. However none of their properties are in the areas you asked about (I guess Paddington is close, but i would not want to stay in that location for two months.) When you say “serviced” do you want cleaning? Someone at the front desk?

I think a lot of these kinds of places are outside the center. I stayed last year in an Adagio Aparthotel and my apartment was huge, but it was in the no man’s land of Brentford. They do have a property in Stratford where you’d be 10 minutes from an important tube station. The link Janis posted has lots of places but anything super central is going to be really expensive (by my standards, maybe your budget allows that.) having a quick look though, I saw places I would stay in, there are some decent and well connected areas like Ealing Broadway there, for instance.

booking.com is also a place to look…
