The apartment was quite clean and nicely decorated with sports + travel themes. We had all the appliances we needed for coffee, chargers, tv, etc. Also close to 2 different metro stations + many bus lines.
The neighborhood is very quiet and clean as well. Felt safe and friendly.
Have in mind that the apartment is in the third floor and has no elevators.
Overall we had a great experience in Sergio's apartment and it did help us to enjoy our time in London a lot.
