Daniel, Erez's friend, met us promptly outside of the flat and was very helpful showing us round and answering any basic questions we had. He was friendly and more than willing to recommend places if we needed.
The apartment itself is relatively well equipped, authentic to the description given, with beautiful big windows overlooking a large enclosed residential courtyard, opposite ivy covered buildings-really beautiful! It also felt safe and calm in a charming neighbourhood peppered with independent cafes and restaurants perfect for breakfast in the early sunshine. It's about a 10 minute walk from the nearest U-Bahn station making it an ideal location for sightseeing too.
The wifi was fast and very much efficient.
In particular we loved the shower! Great strong jets of water perfect after a day's walking.
The only semi-negative thing is how chilly the apartment got at night/early morning.. But we felt this was more the weather's fault than the apartment!
Would definitely recommend!
