Anthony is prompt and helpful, and is very frank and open about advising guests about the plusses and minuses of his place. Rooms are smallish but very clean, and the apartment is homely rather than glamorous. The acid test of any accommodation: we extended our stay (two weeks) for an extra night, and asked if we could come back again later. The ground floor (but very secure) location is very convenient, although the entrance is not too prepossessing.
Note for light sleepers: A busy road much-favoured by trucks, motorbikes and cars with good sound systems passes right outside the windows. This did not put us off, but it needs to be considered if you are likely to be bothered. Other residents of the building are very quiet.
Everything works: wifi, TV, hot water, shower, heating if required, and the bedding was comfortable. The best part is the Williamsburg location - great cafes and restaurants and good subway access to the M and L.
