This is a great value hotel, the reason it is a bit cheaper than the others is that its location is a little bit out of the main centre of the city. It is however in easy walking distance of a metro station and the tram stops just up the road.
Get yourself a 3 or 5 day travel ticket when you arrive, you can use it on tram, bus and metro but MAKE SURE YOU VALIDATE IT AS YOU START YOUR JOURNEY!
