Unfortunately our stay was not really pleasant.. the noise in the flat is AWEFUL! Windows are just like paper concerning the noise ... and we were barely able to sleep ! We were awaken by the noises several time per night ... together with an uncomfortable bed (you can feel all the springs in the mattress ... ) and that awfully noisy fridge we had to unplug as it was so loud.
Heating system is also a problem. Even if set at a normal temperature (22 Celsius) that thing is messy ... once blowing cold, then blowing hot ... hard to sleep in that conditions as the blowing thing is just up the bed !
Great things though : location is not bad (though noisy (road & loud people at night)), check in method was great as well
