We enjoyed our stay at Marija & Zvonko's flat. Marija was waiting for us at the flat when we arrived and gave us a quick tour. The flat looked exactly as pictured and was clean and welcoming. There were even some nice fresh flowers on the table!
The flat is reasonably close to the tube station (10 minute walk) which worked out perfectly for us.
The apartment was a great place to use as our home base for our stay in London.
