I stayed at Josh's place for three months during a research stay and I loved it there. It didn't take long for me to feel at home. The apartment is spacious and equipped with basically everything you might need during such an extended stay. If I needed anything else, Josh was very accomodating and very quickly organised further things (like a kettle or a portable heater when the heating in the flat failed at one point). Communicating with Josh was very easy since he is not only a genuinely nice person but also attaches great importance to providing his guests with a stay as comfortable as possible. Maida Vale is a quiet and pretty residential area, which for me (as I was often working from home) contributed to a good working environment. It is also well connected by public transport to the rest of London and very safe (when walking home from the closest Underground station - Warwick Avenue, about 8 mins walk - I never felt uneasy). I can certainly recommend staying at Josh's apartment!
