Great, clean and modern apartment. The sofa bed is comfortable. Great little balcony too! There is only one set of keys which can be a small issue if you are travelling with people who will want to do their own thing, but you can leave the key with the concierge (a little bit annoying each time though as you have to write the recipient's name on an envelope etc - it just takes time).
We had an early flight out of London and one of the house rules is that you need to leave the apartment clean and tidy, take the bins out, put towels in bath, make up the soft bed into a couch again etc - wasn't the best thing to be doing at 4am in the morning. But it says this all in the house rules so just make sure you read them all before you book this so you aren't annoyed when you arrive!
Jane was responsive to my emails and very friendly!
