Jonathan's flat was WONDERFUL! There is the 5-floor walk-up but once our heavy luggage was in, it was totally fine. The apartment was much larger than we were expecting and felt so cozy. It was nice to be able to spread out and we really enjoyed the space. The location was amazing and we felt that we could walk almost everywhere. Jonathan and his mom, Sylvette, were so kind and accommodating, and excellent hosts. We will most definitely return to this apartment!
