Lovely little apartment! You can't get a better location, we ended up just walking everywhere, no need for a metro pass!
As it's so central there was LOTS of traffic noise, motorbikes revving loudly at all hours of the night, so bear that in mind.
Bed was ok, a bit hard though and needed more pillows. It didn't help that the one provided kept falling down the gap behind the mattress! But I guess that is to be expected partially with a folding bed.
We had some issues at check in. Instructions were to ring the bell, but we had been delayed by an hour coming from the airport, and my phone was having issues, so I couldn't let them know. No answer when we then got to the door. (only 7pm so it wasn't too late)
I had to find a restaurant a few doors down to connect to wifi and let them know that I was there. But there was no response from their doorman, so we were eventually luckily let into the building by neighbours after being stood outside for 25 minutes.
