If this place is available, BOOK IT. Len is great, he's very friendly and very responsive when you message him and even answered some of my messages promptly at around midnight!
The apartment is located on a quiet street, we never had an issue with traffic noises, or loud locals after a night out, which helped us relax and rest when there. Apart from the confusing layout of the tram stops, the apartment is well situated for using the public transport within the city (two minutes away from the nearest tram and 15 minutes walk to the metro).
Of course the main selling point of this location is Patrick, a lovely companion who may greet you for breakfast, or grace you with his presence in the evening!
The area is home to many small and large eating establishments, and I highly recommend visiting some of the smaller restaurants as you may find a new cuisine you never knew about.
