Mark's place is very conveninent is you're looking for somewhere close to the centre of the city. The apartment is clean and offers good value. The bed was very comfortable and although the bathroom isn't en suite, it was only for our use. The only minor niggle was with the temperature of the shower which only needed a small turn to go from cold to very hot, but I have made Mark aware of this.
Mark is a very accommodating host - he was happy for us to arrive at after 10pm and he greeted us personally rather than sending us details of how to let ourselves in.
I would recommend his place for anyone wanting to stay near the city centre.
