This was our first time in London, and the location of this place is amazing. Very well connected to Underground lines, bus lines, restaurants, bars (Starbucks is literally next door!) That being said, the apartment does not face the road (faces in toward the rest of the parts of the building - if that makes sense) so it is very quiet and peaceful.
Check in was smooth, you get a set of keys to keep for the duration of your stay. Wynn let us keep our bags in the common space after we checked out till the end of that day. We picked them up and dropped the keys off on our way out.
Room itself is quite spacious and you get a private toilet. There is a separate bathroom (that is shared) with a shower + tub.
Breakfast included tea, coffee, milk, cereal, fruit, bread/toast, choc chip brioche rolls, nut butters, jam.
Wynn was very courteous and responsive. Will definitely stay here again!
