The best thing about this flat is the location - Fitzrovia is a lovely area and just a few minutes walk from Bloomsbury, Marylebone, Mayfair, Oxford Street and Soho. Most of London's sights can be explored on foot from here, but there's also three underground stations that are just a few minutes walk away - so you're directly connected to pretty much every line on the underground network! I wouldn't recommend driving here, as the parking is expensive - although it is free in the evenings and all day on Sundays.
The other great thing about this location is that despite the fact that it's so near everything, it is quiet. The street isn't a through road for passing traffic, yet the centre of the city is on your doorstep. It's also really safe, there's an embassy across the road and a few celebrity neighbours too!
Chloe was really helpful before, during and after my stay. She let me drop off my bags early, and leave them there all day on the day that I checked out. She also checked me in personally, and pointed out the local shops, transport links and recommended cafes and restaurants. The wifi is fast and works well throughout the apartment, and the kitchen is well stocked with all the things you might need. Towels, shower gel, tea, coffee etc are provided too. The flat is spacious with high ceilings. The bed is a full size double with a good quality mattress. And the shower is hot and consistent.
Overall, a faultless stay! I'd recommend this property without hesitation, along with Chloe who is the perfect host.
