Unfortunately my stay at Ronald's was not pleasant of comfortable either during or after the stay due to cleanliness and communication.
The major problem causing me to be super unconfortable was dirty bedding (sheets and the duvet) that smelled and had dog and human hair and some stains in them. I asked it to be changed, but apparently that is the only set, so it went into the wash. As I had made a last minute booking it was then too late, as I wanted to sleep already. Slept with my own sleeping bag.
Additionally there was some stains on the table and the bathroom (which is private - a bonus) had grime. Overall it made me feel he was not ready to host that evening.

Ronald was super friendly when I was there, but once I asked for a refund the tone changed completely. It felt like he took an offense and it to be personal.
The appartment itself is good with kitchen to use. There is a super friendly dog (and dog hair + smell everywhere) who is keen to play and spend time. Suits for ppl who love dogs.
The room is small and has it own entrance leading to back alley with a parking space. There is a sofa that is converted for sleeping, however there is no extra matress on it and it is not that big, so if you are any taller this is probably not that comfortable for you. There is also a metrocard that can be used.
