I would highly recommend Solonas's apartment. The check in/check out experience is easy, the apartment is really spacious especially by London standards and it was spotless. I'm really sensitive to noise and there was zero neighbour or street noise in this apartment which was a dream. The bed is really big and possibly one of most comfortable I've slept on. The kitchen is fully equipped with everything need to cook at home . I also worked from the apartment and the wifi is well able to host multiple video conferences. The TV is a smart TV so it's set up for all multiple on demand apps including netflix, prime, iplayer etc. The couch is really large and comfortable for a night in.
Location wise the apartment is within a 5 minute walk of two supermarkets, there are several bus routes nearby as well as being short walks to both Old Street (6/7 mins) and Angel (12 mins) tube. Lot's of great cafes nearby also for a morning coffee.
Solonas himself is a great communicator and very kindly accommodated some changes in my travel dates. Overall a really great experience and I would stay again in the future.
