The apartment with 1 bed room is great. The bathroom and kitchen are clean and modern.
Paloma prepared the apartment as discussed, but she did not turn on the heating prior to our arrival. (The main negative point of our stay)
The apartment was very cold, which did not generate a merry arrival.
We figured out how to turn the heating on and by the following day the apartment was warm.
The kids loved the sleeping area above the kitchen, but we couldnt let them sleep there, since a barrier was missing. We put the kids in the bed room and slept on the sofa beds in the studio, which was fine for a couple of nights.
The location of the apartment is great, easy to get to and easy to get around. Pimlico Fresh around the corner has a great breakfast.
Another recommendation is to fix up the cable mess right in front of the door to the apartment. Not sure what cables they exactly were, but cables hanging out in the staircase - especially with kids - is never a good idea.
