While we appreciate your feedback, there are several points that I would like to comment on. While the accommodation is indeed used by some international students on a longer-term basis, we typically have 1 - 2 people staying with us per week on a shorter term basis. The fact the there are also longer term tenants in the house should, in my opinion, increase your safety and comfort and security- it shows that they are very happy in the accommodation. If everyone was very short term, then there is no doubt that there would be a less secure feeling.
As far as locks on doors are concerned - this is only typically seen in hostels, not in private accommodation... in private accommodation, it would just look weird - but that's just our opinion.
When you checked in, we asked if everything was okay, and to contact us if you had any issues - the fact that you didn't get in touch led us to believe that you were happy with everything. If you had any concerns about the cleanliness, we would absolutely expect a call - we would even have appreciated a call so that it would have been dealt with immediately!
The bed - I'm sorry, but every bed in the house is less than 8 months old - brand new beds, with brand new orthopedic mattresses. I know that not every bed suits every person - some prefer soft beds, others prefer hard beds - but this is down to personal taste, rather than it being anything that can change for everyone who stays with us.
We are genuinely sorry that you were not 100% satisfied with your stay, and I can assure you that we will only strive to do better for all our future guests. If you do indeed change your mind, you are welcome back anytime to stay with us and we will work hard to ensure that your experience is hugely improved.
