Atma's apartment was great. I ended up getting delayed and Atma made arrangements for me to receive the keys elsewhere since I arrived 6 hours later than expected - this process was not ideal, but he made it easy for me to retrieve them and get into the apartment right when I arrived. The apartment was clean and had everything I needed. The location was perfect and made it easy to get everywhere I needed to go mostly by foot. I'd definitely stay again if in London.
