Great flat in Berlin! Very spacious and clean. The A/C was a plus during the heatwave in Berlin (and Europe). The temp outside was around 90 degrees F but returning to Elen's apt made us feel so comfortable. Things to keep in mind, this is an attic apartment so there are stairs to climb with your luggages. This would normally be okay for us as we are fit but it was hard during this incredible heatwave! But again, the A/C was such a great addition to the apartment. This is not really normal in Berlin as the weather is usually temperate. The terrace was a great addition. Very comfy and happy with our stay. Thank you!
