The apartment was wonderful! Just as described and plenty of room for the 4 of us. Right I'm the middle of practically everything we wanted to do, with the castle being the furthest away at a 30 minute walk (but can get team there, too).
All good clubs, bars and restaurants were within an 8 minute walking radius but still tucked away enough that no noise from the streets disturbed us whatsoever.
Would definitely recommend and would visit again.
