We stayed 5 days in this apartment and thoroughly enjoyed all the sites in London. The apartment is a 10 minute walk to two stations which allows access to the tourist sites in 20-35 minutes. The tube is easy to use with tap in tap out credit cards. Islington area also seemed safe and came with several pubs and restaurants to access.
The apartment requires walking several flights of narrow curving stairs. Bring luggage up and down is a challenge for several in our group and we were all happy to escape uninsured.
The kitchen is well equipped with microwave, dishwasher coffee maker etc. there are three bedrooms and two full baths which was good for our group of five adults.
The bedrooms are tight and there is little room for storage. Several of the closets are locked and or occupied by equipment so unpacking and luggage space is very limited. The apartment is heated but only has fans for cooling. During our stay the upper level reached 31 degrees C even with the fans. This temperature left the apartment quite uncomfortable and sleeping was limited. We were thankful for the fans.
Our group agreed we would not use this apartment again. The main issues being the stairway access, temperature and lack of storage.
