This is great apartment.
It's large! It has a separate bedroom, a nice large separate living room and a very nice kitchen. Not like some other places in which everything is crammed into a small space. This apartment is very spacious.
We prepared some of our meals ourselves and had them in the apartment and it was great.
The view to the park is beautiful (we saw a sign that there will be some construction in the park soon, so that might change).
Location is great! 5 minutes walk to Euston station! Very convenient.
At the same time, the apartment itself is in quiet street without any traffic. There was a little noise from the nearby bar, but it didn't bother us.
Notes: the apartment is on the second floor without elevator, and there is no A/C. Both these facts are clearly stated and we took that into consideration.
Price was very reasonable for this location.
All in all - we enjoyed our stay very much. For us it was a 5 star stay.
