We didnt get to see much of david because we were out exploring till late at night. Had problems with getting the key to work and he was very helpful and offered to leave work to meet us (fourtantly for him we got it to work). His apartment is a little on the outskirts of the city but the metro makes everything close. It is small but tidy and well organised and with a nice homely feel. Devid was very accommodating and friendly and we felt very comfortable during our stay.
