We booked this apartment solely based upon its location and the availability of a rooftop terrace. The location is absolutely top-notch! Great restaurants close by, a supermarket just a few minutes' walk away, and easy walking distance to buses, Oxford Street, Regents Park, etc.
The rooftop terrace, however, was a disappointment. In order to access the roof, one must climb several precipitous stairs (no handrail and a bend in the staircase), and lift up the very heavy skylight using one's back to lever it open -- all the while balancing on the top steps holding on to the side of the rooftop. If you are young, fearless, and agile this will not be a problem, I'm sure. However, we are in our seventies, spry and active but not sufficiently brave to make this ascent more than twice during our visit. Unfortunately, the washing machine is also located in a small shed on the roof, so climbing up those steep stairs with a load of laundry, without the aid of a handrail, is really risky.
The flat itself is perfectly adequate. In order to have a rooftop terrace, of course, one is located on the top floor. There is no lift in the building which meant climbing several flights of stairs with luggage and shopping. Perhaps I missed mention of this when reading the description of the property but it came as a bit of a shock upon arrival. We were asked to be very careful with the bedroom closet mirrored doors as they were broken. My husband repaired them and we had no further issues.
We had a pleasant stay, thoroughly enjoying the neighbourhood and taking long walks daily in Regent's Park. I would probably recommend the apartment to a young friend but warn anyone older than 65 about the risks of the stairs leading to the rooftop terrace and the absence of a lift in the building.
We can recommend the local restaurant "Getti". The food was great and the manager, Nilson, was so friendly and attentive. We returned several times during our stay on Thayer Street.
