The location is 10/10. Right in the heart of Covent Garden, 5 meters away from the main market. All major bus & train lines are within walking distance. The apartment was clean, nice, and cozy. Some amazing cafes, and restaurants all around. Shopping too. The bedroom and balcony have lovely views of the garden of St Pauls's Church right next to it.
We found ourselves spending a lot of time on the couch and on the balcony. The bed, rather mattress in the apartment is another 10/10. I don't think I've slept this sound in a long time.
The staff was AMAZING! They helped us with a smooth check-in and check out incl helping us with some personal errands that we ran while we were there.
The only downsides would be, If you are traveling with children or older adults, the apartment is a steep climb up 4 floors. The climb is narrow and the steps are small. It could be difficult. I also wish the apartment came with a cleaning service for a stay over a week and enough stock of toiletries and kitchen snacks, coffee, etc. Another note - If you use a lot of uber or taxi services, being dropped below the apartment might be tricky because a lot of roads around Covent Garden have been made into bicycle-only lanes. So a bit of a walk will happen
Overall experience 10/10. Would definitely book again when we come back to London.
