I stayed at Mark's apartment for almost 2 weeks. The place is exactly as shown in the pictures. It is kind of small but cosy and has everything you need.
Even though it is listed as a 4th floor (with no elevator), it is a 3rd floor (not counting ground) and the way up is quite easy.
Mark's apartment is just a few steps away from the main street and all the pubs.
I highly recommend that whoever is reading this comments stays at Mark's!
