Niko's place was fantastic! The flat is spacious and well decorated. The bed is comfortable, and the bathroom/kitchen appliances are modern and work well!
The location is also amazing. 3 minute walk to the tube, and a ton of buses stop right in front of the flat, making it very convenient to get to any part of town you want to visit. The Angel area itself has a lot of restaurants/pubs/you name it, and the small street behind the apartment has pop up shops and makes for a very picturesque walk. The flat is right across from a park, and the view from the living room and front bedroom is beautiful, just like the pictures show. Even though it is a busy street, the soundproofing of the windows is great so the flat is actually very quiet.
Even though I didn't get a chance to meet Niko, I could not have asked for a better host. We spoke via phone prior to my arrival, and she was very very responsive via email. She was very accommodating with check in/out, which my older parents appreciated, and provided us with all the information we needed to make our stay a very pleasant one. :-) Overall a fantastic experience. 10 out of 5 stars. Will definitely try to stay at Niko's place again in the future.
