Looking for room / flat to rent

I’m looking for a spacious clean flat starting mid to end of August. I’d like to have a double room with an ensuite. Preferred location is central London (west central). Neighbourhoods close to Mayfair areas like St John’s Wood, Marylebone, South Kensington, & Earls Court. I have a full-time office job five days a week in Marylebone. Usually leave the house by 8 am and come back at 7 pm. Spend most of my week at work and travel back to Spain to visit my family when I have extended breaks. I don’t like partying, no partner and I’m very clean and tidy. During my free time, I enjoy trying new restaurants, going to Pilates and long walks, meeting my friends. ⭐️
