locations is perfect. 3 different underground stations are reachable within 5 minutes walking.
you can use the bus line 23 all night long for going out coming back far after midnight.
the main bed was comfortable but the "bed sofa" could have been more. i recommend staying for 4 people only with children because with more than 50 kg you feel every bedspring.
overall i would book it again for 2 persons.
