Petr's apartment is very nice, warm and clean. I was there with my family and everyone was happy with the choice. There is also an excellent Internet connection, we could easily watch Netflix streaming movies.
The area is very quiet and is full of cute squirrels and, in the evening, you can also see some foxes. Good restaurants, pubs and small supermarkets are within walking distance.
It is very convenient to reach central London, in 10 minutes on foot you can reach Blackheath station where there are frequent trains that arrive in London Bridge in 10/15 minutes.
Petr is a very kind and helpful host, I hope to be able to return to his apartment soon.
