Stayed in the first floor flat for a week (as the one we booked was having the floor re-done). It was clean and comfortable :) The bed was REALLY comfortable. I would say that a shelf space or a draw to put clothes in is lacking in the main bedroom, but everything else that we could have needed was there. It was really helpful, for me, to have access to cleaning products as we were there for some time. The water pressure was really good. The location of the flat was excellent; it was a short walk from the metro and walking to the centre of town was 10 mins. There are so many good bars, restaurants etc nearby and more within short walking distance.
The light from the outside was blocked out significantly for me (who becomes a light sleeper with light and/or noise).
Cons -
The wireless was slow at times. The walls of the building are a bit thin so you can hear the neighbours at some points. The plugs by the bed are only suitable for EU plugs and not convertor ones, so we had to leave our phones charging in the living-room (which meant getting up (and walking) for the alarm.
The work being done on the flat above had men working one day between 8am-8pm meant that neither a relaxing morning or evening could be had. I understand this is not the norm.
The negatives of the flat, which is out of the control of Manuel, is that there was a noisy neighbour in the building who decided that shouting at each other between the hallway and the flat, whist sporadically banging the floors or wall, and smoking between 2-3am one morning was acceptable.
It's lively outside on the weekend so, if you're not part of it, I would suggest brining ear plugs.
Overall I really enjoyed my stay here and would recommend and stay again.
