London for 3 to 4 days

Ciao,

I ll be coming tomorrow to London from Milano for 2 to 4 days max.
I will be working in the city on wednesday and thursday, but I ll be free in the evenings, and also Friday and Saturday.

I am wondering if you have some time to meet up for a coffee, drink, may be more :)
I am also wondering if you can offer me a couch for 1 night or 2, that would be kind of you :)

If you cant, no problem and lets only meet :)

Let me know your thoughts :)

PS: Tuesday and Wed evenings I ll be staying in a hotel in the city central

Thanks
Younes
